LED Ring Light with Polarizing Filter for Microscope Polarized Illumination Key benefits Polarized lighting for improved contrast and clearer detail: builtin 35 mm polarizing filter reduces reflections and enhances visibility of birefringent and reflective specimens. Precise, even illumination: 120 LEDs produce uniform 6500 K white light for neutral color rendering across the field of view. Fully adjustable brightness: smooth linear dimming from 0100 percent lets you set the exact light level needed for observation or imaging. Easy integration: 62 mm inner mounting diameter fits common microscope objectives and adaptors while the compact form minimizes obstruction. Reliable in lab and environments: designed to operate within normal indoor temperature and humidity ranges for consistent performance. Product highlights Light source: 120 LEDs, 6500 K white Polarizing filter: 35 mm diameter, included Mounting: inner diameter 62 mm, outer diameter 90 mm, thickness 33 mm Working distance: effective illumination from 40 to 120 mm Power: AC 110240 V, 50/60 Hz with included power adapter Dimming: linear 0 to 100 percent brightness control Operating environment: 0 to 40 C, 20 to 85 percent RH Why this ring light solves common problems Reduces glare and surface reflections that obscure fine detail on polished or translucent samples. Provides consistent, shadow lighting to improve visual inspection and imaging reproducibility. Precise dimming control prevents overexposure when capturing photos or viewing sensitive materials. Compact 90 mm outer diameter and 33 mm thickness keep the illumination close to the optics without blocking access. Compatibility and dimensions Designed for microscopes and inspection optics with a 62 mm inner mounting diameter. Outer diameter 90 mm, thickness 33 mm, polarizing filter diameter 35 mm. Effective for sample working distances between 40 and 120 mm. Package contents 1 x 120LED ring light 1 x power adapter 1 x polarizing filter Typical use scenarios Polarized microscopy: Inspect thin sections, crystals, and other birefringent materials where controlled polarization reveals structural detail. Electronics and PCB inspection: Reduce reflections on component surfaces to detect soldering defects, cracks, and surface contamination. Material and quality control: Examine fibers, films, coatings, and polished metals where minimizing glare and enhancing contrast is critical. Practical notes Ensure your microscope or adapter supports a 62 mm inner mounting diameter for direct fit. Position the ring light at a working distance between 40 and 120 mm to achieve uniform illumination without vignetting. Operate within specified temperature and humidity ranges for reliable performance. This LED ring light provides stable, polarized illumination with flexible brightness control and a compact mounting profile suitable for microscopy, inspection, and imaging tasks requiring improved contrast and reduced reflections.
