3 Overview

Visible foreign matter is present in injections, ophthalmic pharmaceutical preparations in a liquid solution, under specified conditions, can be visually In observed insoluble material, typically having a particle size or length greater than 50μm. Clarity detector is based on light inspection method using visual methods, within the time specified in the illuminance and provisions, respectively In black and white background of the instruments to detect visible foreign matter. Clarity light detector system consists of a dedicated trichromatic illumination continuously adjustable fluorescent lamp composed of digital photos Meter part (the photoreceptor), time control systems. Figure 1 schematic clarity detector A- with a fluorescent light shading plate; B- reflective white background (the inside of the visor); C- non-reflective black background; D- white background and is not reflective of the bottom (for checking colored foreign matter); G- time display section; H- illumination display portion; E- one (or two) Illuminometers; F- clarity illuminance detector probe ...
