LED Light Source for Stereo-Microscopy, Macro-Photography and Machine Vision
The LED Light Source can be used for fluorescence or other oblique illumination with stereo microscopes or as a spot light in machine vision systems. It can have a white or 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 can accommodate 25mm or 30mm excitation filters. Intensity is controlled manually with a knob, and on-off switching may be controlled by a TTL trigger signal. An emission filter holder for 2"x2" square filters is also provided.
Features and Specifications
Wavelength options: cool white, neutral white, warm white, single color - 365, 385, 395, 405, 448, 457, 460, 470, 505, 523, 567, 590, 617, 623, 660, 740, 850, 940 nm peak. More wavelengths available upon request.
Can be used for fluorescence illumination with stereo-microscopes, for macro photography, or in machine vision systems. See examples here.
A self-contained unit with integrated driver reduces required bench space and cable clutter.
Collimator has aspheric condenser lens: Ø30mm, FL 26.5mm, NA 0.522 and accommodates Ø25mm or Ø30mm excitation filters. Excitation filters are available from several manufacturers, e.g., Chroma, Semrock, Omega, MidOpt.
Emission filter holder for 2"x2" square filters. Emission filters are available from several manufacturers, e.g., Edmund Optics, Thorlabs, MidOpt.
Adjustable focus with focus lock.
Manually variable intensity from zero to full.
TTL input for instant on-off switching (BNC connector).
Extra quiet fan for cooler operation, higher and more stable light output.
Requires 12V, 15V, or 24V DC power supply with barrel connector 5.5mm/2.1mm, + inside, - outside.
Can be powered by a battery and used in the field without power mains.
Electrical: 120/240V, 50/60Hz.
