Up for auction is a brand new, genuine Olympus KB-4 Blue Interference Polarizing Filter (45mm). This premium optical filter is a crucial accessory for ensuring color-corrected observation and accurate image documentation in specialized polarization microscopy setups.
Key Features & Optical Benefits
Color Temperature Balance: Shifts the warm yellow-orange spectrum of standard tungsten or halogen illumination into a crisp, daylight-balanced neutral white. This provides accurate color rendering when documenting birefringent, geologic, or material samples.
Polarization Optimization: Specifically engineered as an interference-coated filter to maintain light path integrity within cross-polarized (polarizer/analyzer) pathways without introducing unwanted optical strain or artifacts.
Reduced Eye Fatigue: Corrects illumination to a soothing daylight-equivalent background profile, significantly reducing eye strain during long laboratory sessions involving crystal analysis or manual structural tracking.
Hardware Compatibility
This standard 45mm diameter drop-in filter fits seamlessly into the light ports or filter collectors of a wide range of microscope frames:
Olympus Microscope Series: Drops directly into standard 45mm light wells on classic and modern frames including the BH, BH-2, BHTP, IMT-2, as well as BX, CX, and IX series bases.
Universal Fit: Compatible with any alternative microscope brand (such as Nikon or Zeiss) that utilizes a standard 45mm filter holder or collector lens recess.
Typical Applications
Polarized Light Microscopy (PLM): Enhances contrast, visibility, and accurate coloration of birefringent structures in mineralogy, geology, crystallography, and material science.
Digital Photomicrography: Corrects the color temperature at the source, allowing digital CMOS/CCD cameras to capture true-to-life images without requiring heavy software digital tint adjustments.
Item Condition
Condition: Brand New! Pristine optical glass with zero scuffs, scratches, or delamination issues. Perfect, clean, and ready for immediate laboratory deployment.
