Microsope
Video Cameras with Built-in Digital Imaging
[Specifications] [Samples
Images]
Digital Edge Sharpening convolution filter operates in real-time
to expand the finedetails of soft-focus or low contrast images. The unique
filter enhances video prints andcomputer images to more closely resemble
the subjects as viewed in the microscope oculars.
Digital Contrast & Brightness Enhancement enable control of video gain and offset toimprove dim, low contrast images due to fading and weak fluorochrome emissions.
The Video System Controller contains a built-in 1.5 megabyte 24 bit frame grobber to allowfreeze frame imaging. No external microprocessor is required. The controller is preprogrammed to withstand the rigors of a multi-user environment.
Extended Sensitivity for Imaging of all Microscope
Techniques
On-Chip
Integration permits exposure from 1/10,000 to 4 seconds for the DEI-470
and upto 2 minutes for the DEI-470T. This exposure system operates manually
or automatically toaccurately display samples ranging in illumination from
dim fluorescence to normalbrightfield viewings.
The DEI-470T remote camera head produces extremely low dark current to provide true8-bit dynamic range by utilizing a Thermoelectrically (Peitier) Cooled CCD.
Cooling to 37°C below ambient temperature allows display of noise-free images which are beyond human vision.
