LED Light Source for Microscopes and Custom Optical Systems

The LED Light Source is intended for epi-illumination (fluorescence, reflection) or trans-illumination (bright field, phase contrast, DIC) in microscopes and custom optical configurations. It can have a 10W white chip or an up to 5W single-color chip; a wide selection of colors is available. This single compact unit contains the LED chip on a heatsink and a constant current driver; it screws into a collimator, which has a microscope-specific mount. Intensity is controlled manually with a knob, and on-off switching may be controlled by a TTL trigger  signal.

Features and Specifications

• Wavelength options: 10W - Cool White, Neutral White, Warm White, Single color up to 5W - 365, 385, 395, 405, 457, 460, 523, 590, 623, 660, 740, 850, 940 nm peak (different color chips have different power). More wavelengths available upon request.

• For epi-illumination (fluorescence, reflection) or trans-illumination (bright field, phase contrast, DIC).

• A self-contained unit with integrated driver reduces required bench space and cable clutter.

• The same unit can be used for microscopes and for custom optical configurations. Compatible with Thorlabs' tube system (SM2) and Edmund cage system.

• Adjustable focus with focus lock.

• Manually variable intensity from zero to full.

• TTL input for instant on-off switching (BNC connector).

• Extra quiet fan with adjustable speed for cooler operation, higher and more stable light output.

• Can be used for oblique illumination with stereo-microscopes or machine-vision systems.

• Requires 12V DC power supply with barrel connector 5.5mm/2.1mm, + inside, - outside.

• Can be powered by a 12V battery and used in the field without power mains.

• Size and weight (not including collimator) Ø 63mm, 150mm long, 0.4 kg.

• Electrical: 120/240V, 50/60Hz, ? W max

• Exposure time on standard specimens: bead slide, autofluorescent plastic.

• Aspheric collimating optics provides uniform illumination.
