Description
LED ring light RL4-66-S40 is a segmented cold light source for laboratory optical instruments and lamp assemblies. It features a ring diameter of 66 mm, a colour temperature of approximately 5600 K and four independently usable segments, supporting flexible illumination patterns for inspection and imaging. The ring form factor promotes even circumferential lighting around the working area and can help manage shadows during sample observation. Supplied as 1 pc and weighing 0,790 kg, the unit is intended for the LED-series and works with matching accessories in that family. From manufacturer Starlight Opto-Elect, the RL4-66-S40 belongs to cold light sources chosen when cooler, stable light is preferred over conventional lamps. Segmented control supports tailored lighting on stereo-microscopy support setups, optical workstations and general laboratory inspection stations. This single-piece ring light integrates into professional LED-series configurations for optical instruments and related cold light applications on the laboratory bench.

Questions about LED ring light RL4-66-S40, for LED-series,, 1 unit(s)
What is this article?
LED ring light RL4-66-S40, 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.
