Digital Microscope Frequently Asked Questions  (FAQ)       Updated: 4/24/2014     

 

What is the main advantage of using HD High Definition digital microscope?

 

The digital microscope display resolution is 1080p at 30 frames per second or 1080i at 60fps, so it’s ideal for real time inspection and assembly application.  Typical HD digital microscope has HDMI output, which can be connected with accessories that accept HDMI input.  YSC FreeScope FSHD digital microscope also has parallel video output, which can be connected with common video accessories.  For watch comparison of HD vs. SD (standard definition), please go YouTube link at nVidia or Samsung.

 

What are the main advantages for using digital microscopes?

 

With digital microscopes, clear images can be seen via monitor, so less eye stress and physical fatigues.  Digital microscopes can be configured with different accessories for saving image, video recording, image processing and measurements.  Monitor can also be viewed together

for training and discussion purposes.  Video images can be networked on computer for discussion with outside vendors or suppliers.

What are the common CCD sizes for digital microscope cameras?

 

¼”, 1/3”, ½”, 1/1.8” are the most common sizes. 

See PDF link for other sizes.

 

What are the common CCD sensor types for digital microscope cameras?

 

CCD (Charge-coupled device). 

CMOS. 

 

What is the working distance for digital microscope?

 

Working distance is the distance from the lens to the viewing sample at focus distance of digital microscopes.  If you need longer working distance like 6 inches or more, then you can go with FreeScope digital microscope.  Longer working distance is better if you need room for assembly or inspection applications.  In general, working distance is longer when at lower magnification of digital microscope.  Working distance is shorter when at higher magnification of digital microscope.  If you need help in choosing the right digital microscope for your application, please call us at 510.226.0889 or info@ysctech.com    See PDF link for full data and glossary.

What is the field of view (FOV) for digital microscope?

 

Field of view is the area that the camera is seeing and display on monitor.  Normal definitions are horizontal, vertical or diagonal field of view.

For example:  With 1” (25mm) horizontal field of view, the 1 inch parts would be expanded to fill the whole screen of monitor regardless of monitor size.  The field of view is not affected by the monitor size use.  However, the video magnification will be affected by the monitor size use.  Even at same 1 inch field of view, the video magnification will higher for large size LCD monitor and lower for smaller size LCD monitor.  See PDF link for full glossary.

 

What is the video magnification for digital microscope?

 

Video magnification is measured by multiplying the size measured on the monitor over the actual size.  For example, if actual size the 1” but measures 10” on the 22” monitor, then you have 10x magnification.  For the same part view under 32” monitor, your video magnification would be increased by 32/22 times.  See PDF link for full glossary.

 

What monitor sizes are available for digital microscope?

 

7”, 8”, 10”, 15” are common for video digital microscope.

22” monitor is common for HD digital microscope.  17” and larger 32” are also available.

17”, 22”, 25” and 27” monitors are available for computers using with digital microscope.

How to choose the best camera?

 

In general both HD and video cameras are real good for real time inspection.  USB Megapixel cameras are good for saving high pixel images.  Normally 2MP (1600x1200) will be good for pint out to letter size (11”x8.5”).  If you want to print out larger than letter size, then you are recommended to use higher pixel cameras.

 

Is higher megapixel camera always better?

 

For real time inspection and taking picture, 1.3mp and 2mp are better because of fast frame rate.

For picture taking purpose and print out to larger than letter size paper, then can go with 21mp or 32mp.

 

How do you determine the accuracy at a particular field of view when using digital microscope measurement software?

 

Measurement software works by utilizing the pixels across the computer screen, so there are no moving parts like XY stage.  At each particular magnification, there is certain field of view across the computer screen.  Base the on the field of view, software can be calibrated to determine the pixel size.  Since the software learned the pixel size, then distance/pixels between 2 points clicked by the mouse on the computer screen can be determined.  Different calibrations can be stored in the measurement software’s calibration manager.  In general, one can use 500 as the rough number of pixels (analog video:  640 h x 480 v) across when using analog digital microscope; and use 1000 or 1500 (2MP: 1600 h x 1200 v) as the rough number of pixels across when using megapixel digital microscope.  Actual number of pixels will be more when using higher megapixel cameras.

 

For example, at 5mm horizontal field of view, using analog video and megapixel digital microscope, accuracy would be about 0.01mm (5/500) and 0.005mm (5/1000), respectively.  In general, user will get higher accuracy with smaller field of view and higher megapixel cameras.

What is unique about FSHD digital microscope camera?

 

Our HD camera has both HDMI and BNC output so you can use HDMI for
real-time viewing and VIC-USB USB capture device to save images. If you want to
view and capture in HD, we recommend you to purchase an HDMI splitter so
one end can go to the monitor and the other end will go to HDMI
capture device.

What are some of advantages for using microscopy cameras over SLR or other digital still cameras?

 

Ease of Setup:
Microscopy camera comes complete with a USB 2.0 cable,
installation CD, electronic User's Guide, microscopy application software,
and power adapter (if required). The camera can be set up on a laptop or
desktop PC in minutes. Visit our "C"-mount adapters page to determine the
appropriate adapter for your microscope, and you're ready to go.

Software:
The INFINITY ANALYZE software package is easy to use and intuitive. It
provides all of the camera control functions to create an optimum image, and
includes calibration, measurement, and annotation tools, along with a number
of image enhancement functions. There is no need to download captured frames
from a memory card, as the images are instantly transferred to your PC as
they are captured.


Display:
Our USB cameras provide continuous video frames to the PC monitor, offering
a far superior presentation of the final image than you would achieve on the
small digital screen on the back of a DSC. The live video mode allows you to
quickly frame and focus the camera image.

Dedicated:
USB cameras are connected directly to the PC. They do not make use
of tiny buttons spread across the camera body or have complex layers of
menus displayed on a miniature screen. All camera controls are handled
through the application panels displayed directly on the PC monitor. Since
the camera only functions when connected directly to the PC, and does not
include any standard optics, it is far less likely to be borrowed for other
use outside of the office, making it a more secure asset in the lab.

Options:
Our cameras come in a wide range of resolutions. Choose the cameras that best
suits your requirements based on the type of microscopy work you perform.
Both CCD and CMOS sensor-equipped cameras are available, as well as a cooled
CCD camera that provides optimal image quality for low-light applications.
Cameras are available in resolutions ranging from 1.3 to 32 megapixels.

 

What are the Drawbacks of Digital Still Cameras like SLR?

- Image sensors and IR filters are not chosen specifically for microscopy
applications
- They typically require batteries that need replacing or recharging
- The optics are not coated or designed to be used in microscopy
applications
- Limited storage space is available on the memory card
- Download is required from the DSC to a PC in order for images to be used
- Tiny buttons and complex layered menus are required to control the camera
- Miniature digital display window to frame and focus images
- DSC cameras are portable and convenient for out-of-office use, from which
they may not return
