Hematology

To record slight differences in a Giemsa stain, it’s important that your camera have excellent color reproduction. Since 100x is a typical magnification for this application, the number of megapixels is not essential.

Observation Method

Flourescence

Fluorescence
Cameras must have good sensitivity and low noise because strong excitation light can damage the sample. Although the signal yield is determined by simple physics (i.e., sensitivity × number of photons), some cameras, like the DP74, have a dedicated feature to shorten and simplify the fluorescence imaging process.

Brightfield

Brightfield
Accurate color reproduction is essential. Since modern microscope illumination is very bright, it’s rare to struggle with noise in brightfield images.

Phase Contrast/DIC

Phase Contrast/DIC
For phase contrast or differential interference contrast (DIC), the DP22 and DP27 have a color mode dedicated to imaging cultured cells.

Polarization

Polarization
Many cameras designed for brightfield observation also work well for polarization due to their accurate color reproduction, such as the DP27 and SC50.

Darkfield

Darkfield
Darkfield is the second darkest microscope observation method, so cameras with high sensitivity and low noise are essential. Many of our cameras, including the DP74, UC90, and SC50, feature special noise reduction image processing for excellent darkfield images.
