Frequently Asked Questions

There are four variants of the pT-100 available.

The pT-100-WHT provides comfortable operation and reduced risk of eye damage as no unwanted UV, spectral performance matched to 100 W halogen, creating consistent images, no variation in colour across irradiance range, removing the need to colour balance, and replaces 100 W halogen lamp housing on most current and older microscopes – quick & easy exchange.

The CoolLED pT-100 is a compact and simple-to-use LED illumination system for transmitted light applications, including brightfield, darkfield, DIC, Dodt gradient contrast and phase contrast.

The pT-100-525 provides phosphor-free illumination centred around 525 nm, a bandwidth which is optimised for the spectral response of most scientific cameras. This allows switching between standard brightfield and fluorescence imaging without the fear of background from a phosphored LED.

The pT-100-770 is a specialised solution for IR contrast techniques such as DIC, Dodt contrast etc. Centred around 770 nm provides the optimal output for deeper sample penetration techniques requiring infrared light.
