Advanced Transmitted-Light Illumination

CoolLED pT-100

Compact, stable and precisely controllable LED illumination for brightfield, phase contrast, darkfield, DIC and electrophysiology.

White, visible and infrared options

The CoolLED pT-100 is a compact transmitted-light illumination system available with broad white output or narrow-band 525 nm, 635 nm and 770 nm LEDs. It provides instant operation, stable illumination and precise irradiance control for routine microscopy and demanding research applications.

LED Illumination for Transmitted-Light Microscopy

The pT-100 brings the convenience, stability and long lifetime of LED technology to transmitted-light techniques including brightfield, darkfield, phase contrast, differential interference contrast and Dodt gradient contrast.

The broad white model is designed as an alternative to conventional 100 W halogen illumination. Its colour temperature remains consistent across the irradiance range, supporting repeatable imaging without regular colour rebalancing.

Narrow-band 525 nm, 635 nm and 770 nm versions provide application-specific benefits, including increased camera contrast, deeper penetration into thick specimens and infrared illumination for electrophysiology and specialised contrast techniques.

Four Output Options Choose WHT, 525 nm, 635 nm or 770 nm illumination.
Precise Control Irradiance adjustment in 1% steps from 0% to 100%.
TTL Triggering Remote on/off control for synchronised experiments.
Mercury-Free Energy-efficient LED technology with no replacement bulbs.

Choose the Correct Illumination

Output Recommended Applications
WHT – Broad White General transmitted-light microscopy and replacement of conventional 100 W halogen illumination. Provides consistent colour temperature across the irradiance range.
525 nm – Green Higher-contrast camera imaging. The phosphor-free output is optimised around the spectral response of many scientific cameras.
635 nm – Red Brightfield imaging of thicker specimens where deeper penetration and reduced phototoxicity are beneficial.
770 nm – Infrared Infrared DIC, Dodt gradient contrast, electrophysiology and deeper imaging through thick tissue samples.

Available Configurations

1.5 m Liquid Light Guide pT-100-XXX-L15-ZZ Available with WHT or 770 nm output only. Includes a fixed 1.5 m, 3 mm liquid light guide.
3 m Liquid Light Guide pT-100-XXX-L3-ZZ Available with WHT or 770 nm output only. Includes a fixed 3 m, 3 mm liquid light guide.
Configuration assistance recommended
  • XXX identifies WHT, 525, 635 or 770 nm output.
  • YYY identifies the customer-specified microscope adaptor.
  • ZZ identifies the regional power cable.

Auckland Scientific will confirm the correct output, light-delivery configuration and microscope adaptor before ordering.

Liquid-Light-Guide Delivery

White and 770 nm models can be supplied with a fixed 3 mm liquid light guide. Remote positioning is particularly useful for sensitive electrophysiology experiments because the illumination source can be positioned outside a Faraday cage, helping reduce the risk of electrical interference.

Liquid-light-guide delivery also provides compatibility with microscopes that incorporate their own collimating optics and accept a light guide directly.

What Is Included?

  • CoolLED pT-100 LED light source with the selected output
  • Remote manual control pod
  • Power supply
  • UK power cable
  • Customer-specified microscope adaptor with direct-fit systems
  • Fixed liquid light guide with the selected light-guide configuration

Optional Accessories
