Multi-Wavelength LED Light Source LEMW-401LG2
JCOPTIX four-color microscope LED sources provide commonly used fluorescence-excitation spectra with stable, reliable, fast switching. They replace high-pressure mercury or metal-halide lamps and mount directly to Nikon, Zeiss, Leica, or Olympus fluorescence microscopes. Touchscreen/computer intensity control and SDKs support further development. Each LED is independently switched and precisely intensity-controlled. The versatile sources are vibration-free, easy to use, and long-lived. Contact support for custom wavelengths. Four-wavelength source with collimated free-space output. Models: LEMW-401C1, LEMW-401C2, LEMW-401C3. User-configurable wavelengths; current-controlled switching/intensity; better stability/life than gas-discharge or halogen lamps; optional Olympus/Nikon/Zeiss/Leica adapters. This JCOPTIX source supports up to 4 wavelengths and has an SM2 internal output. Choices are 405 nm, 470 nm, 500 nm, 530 nm, 556 nm, and 630 nm, with adapters for Olympus, Nikon, Zeiss, and Leica ports. It efficiently combines 4 LEDs into one beam. Matching four-wavelength controllers switch/intensity-control each LED, providing a reliable versatile source without vibration, with easy operation and long life. Four-wavelength source with liquid-light-guide output. Models: LEMW-401LG1, LEMW-401LG2, LEMW-401LG3. User-configurable wavelengths; current-controlled switching/intensity; improved stability/life versus discharge/halogen lamps; optional liquid-light-guide (LLG) adapters. This source supports up to 4 wavelengths through a 3 mm-core guide, with choices 405 nm, 470 nm, 500 nm, 530 nm, 556 nm, and 630 nm. It efficiently combines 4 LEDs into one beam. Matching four-wavelength controllers independently switch and precisely adjust each LED, providing reliable versatile, vibration-free, easy, long-lived operation. Microscope adapters, SM2 external threads. Models: LEMW-401CA1, LEMW-401CA2, LEMW-401CA3, LEMW-401CA4. For Olympus/Nikon/Zeiss/Leica ports; easy stable mounting. JCOPTIX SM2 external adapters connect four-wavelength sources to microscopes. Sources have SM2 (2.035-inch-40) internally threaded outputs. SM2 adapters directly fit Olympus, Nikon, Zeiss, and Leica illumination ports. Liquid-light-guide adapters. Models: LEMW-LOFMG, LEMW-LOF03, LEMW-LOF05. Optional LLG coupling; adapt Ø3 mm or Ø5 mm guides to SM1 standards; SM1 (1.035-inch-40) external threads. These adapters couple LED light into guides, replacing SM2 outputs with SM1 (1.035-inch-40) apertures. An included optic focuses into a guide held by the appropriate LLG-to-SM1 adapter. Guide adapters integrate Ø3 mm or Ø5 mm LLGs into any SM1 (1.035-inch-40) component. Liquid light guides. Models: LLG3-1200, LLG5-1200. Good transmission over 260-700 nm; adapters connect Ø3 mm/Ø5 mm guides to SM1/SM2 components or microscopes. JCOPTIX guides transmit exceptionally over 260-700 nm, with cores 3 or 5 mm and length 4 feet (1.2 m). Large-core guides transmit more efficiently than bundles because they eliminate collection losses from dead areas. LEMW software: matching software for JCOPTIX multiwavelength sources efficiently combines four different-center-wavelength LEDs into one collimated beam. Modes are continuous, internal sequence, external sequence, and external following. Download through the button below for further information.
