Spi 40-085-3 Optical Comparator Chart Reticle 7x

Product Description

The SPI 40-085-3 is an optical comparator chart and reticle designed for use with 7x magnification comparator systems. Measuring 1 inch in diameter, this reticle fits into optical comparator stages where precise dimensional inspection is required. It serves as a reference overlay, allowing machinists and quality control technicians to compare part profiles against printed chart lines directly through the comparator's optical path. This is a standard inspection tool found in machine shops, toolrooms, and manufacturing QC departments.

This reticle is suited for bench-top optical comparator setups operating at 7x magnification. It is used during dimensional inspection of small machined parts, screw threads, gear profiles, and other precision components where visual comparison against a reference chart is required. Typical users include machinists, metrologists, and quality assurance technicians performing incoming or in-process inspection.

Key Features

• 1 inch overall diameter fits standard optical comparator reticle stages
• Calibrated for use with 7x magnification optical comparators
• Functions as both chart and reticle overlay for direct profile comparison
• Single-piece unit packaged individually for easy stocking

Compatibility

Designed for use with optical comparators operating at 7x magnification. Verify reticle diameter and magnification rating against your comparator specifications before installation.

Installation Notes

Reticle installation is typically performed by a metrologist or qualified technician familiar with the comparator system. Power down or disengage the light source before handling optical components to avoid glare or heat exposure. Handle the reticle by its edges only to prevent contamination of the optical surface. Consult the comparator manufacturer's manual for proper seating and alignment procedures.
