Product Overview

The Nikon C-AS Analyzer for Gout is a slider-type nosepiece polarization accessory with an integrated first-order red (lambda) compensator plate, designed for clinical identification of crystal-induced arthropathies. Under polarized light, MSU (gout) crystals appear yellow and CPPD (pseudogout) crystals appear blue when aligned parallel to the compensator axis, enabling rapid birefringence sign determination. The slider format inserts into the nosepiece analyzer slot (requires Nikon C-N6A sextuple nosepiece) without raising the microscope eye level. Compatible with Nikon Eclipse Ci-S, Ci-L, and Ni series upright microscopes. Part number MBN91921. New condition.
