Description
LED ring light RL4-66-NW is a cold light source for laboratory optical instruments and lamp assemblies. With a ring diameter of 66 mm and a colour temperature of approximately 5000 K, it supplies neutral-white illumination suited to visual inspection, stereo-microscopy support and imaging tasks that benefit from even circumferential lighting. The ring geometry helps distribute light around the working field and can reduce harsh directional shadows during sample observation. Supplied as 1 pc and weighing 0,580 kg, the unit is specified for the LED-series and pairs with matching accessories in that range. From manufacturer Starlight Opto-Elect, the RL4-66-NW sits among cold light sources used on the laboratory bench when cool, stable illumination is preferred to conventional heat-generating lamps. Integration into existing LED-series setups supports flexible configuration of optical workstations and inspection stations. This single-unit ring light is intended for professional laboratory environments that require reliable ring illumination for optical instruments, cold light applications and related bench work without multi-piece kits.
This article is part of Cold light sources & lighting, in Microscopy & histology.

Questions about LED ring light RL4-66-NW, for LED-series,, 1 unit(s)
What is this article?
LED ring light RL4-66-NW, for LED-series,, 1 unit(s) is the article on this page. Luminix Health distributes Starlight Opto-Elect for laboratory use. It sits in Cold light sources & lighting, inside Microscopy & histology, in Lab instruments.
A cold light keeps the heat of the lamp away from a living or a melting specimen, usually by a fibre light guide. It is the illuminator for a stereo microscope. Colour temperature matters when the image is photographed. A hot lamp over a dissection dries the sample.
A light microscope forms an image with glass lenses and transmitted or reflected light. A stereo microscope is the lower-magnification instrument for dissecting and for looking at a surface. Fluorescence needs a light source and filters matched to the dye. Histology is the preparation that makes a tissue readable: fixation, a cassette, a section, a stain. The objective's magnification and numerical aperture decide the resolution. The slide and the cover glass decide whether the section sits in the focal plane. Stains and dyes as substances are identified on PubChem. Papers on the methods are on PubMed.
