Discover the future of transmitted light applications with the pT-100 LED solution from CoolLED. Designed to revolutionize brightfield, darkfield, DIC, phase contrast, and more, the pT-100 series offers unparalleled illumination for your microscopy needs. With four distinct variants, including a broad white output and three narrower bandwidths, this LED system is engineered to deliver exceptional performance and reliability.

The pT-100-WHT is a powerful white LED illumination system crafted to replace traditional 100 W halogen lamps. Ideal for histologists and cytologists, this system ensures accurate and reliable diagnoses by maintaining consistent color appearances akin to conventional halogen lamps. Unlike halogen lamps, the pT-100-WHT's color balance remains stable regardless of intensity, eliminating the need for adjustments. Available with direct fit or liquid light guide delivery, this variant is designed to seamlessly integrate into your workflow.

For those seeking specialized illumination, the pT-100-525 offers phosphor-free light centered around 525 nm, optimized for the spectral response of most scientific cameras. This allows seamless switching between brightfield and fluorescence imaging without background interference. The pT-100-635 variant provides a peak of 635 nm, offering deeper penetration ideal for thicker samples and reducing the risk of stimulating light-sensitive specimens. Lastly, the pT-100-770 is tailored for IR contrast techniques, delivering optimal output for deeper sample penetration with infrared light, enhancing detail in thicker samples.

The pT-100 series offers both manual and remote control options for ultimate flexibility. Manual control allows for instant on/off and intensity adjustments in 1% increments from 0-100%. For remote operation, a single TTL for on/off control is available via a BNC connection, with a triggering speed of less than 150 μs. The system is designed for direct fit via adaptors compatible with all major microscopes, with a liquid light guide delivery option available for the WHT and 770 nm variants.

Operating efficiently, the pT-100 requires 100-240 V a.c., 50/60 Hz, and consumes only 1 W in standby and 20 W at full intensity. The light source measures 66 mm in diameter and 128 mm in length, weighing just 0.42 kg, making it a compact and lightweight addition to any laboratory setup.
