Spi 40-143-0 7x Magnification Illuminator Comparator

Product Description

The SPI 40-143-0 is a 7x magnification illuminator designed as an accessory for optical comparators used in precision measurement and inspection work. It attaches to compatible SPI comparator models to provide enhanced illumination and magnification, making it easier to examine fine surface details, part profiles, and dimensional features. Powered by C batteries, the unit operates without a tethered power source, supporting flexible use at a workbench or in the field. Metrologists, quality control technicians, and tool room personnel are the primary users of this type of accessory.

This illuminator is intended for use in quality assurance and dimensional inspection environments where optical comparators are part of the standard tooling. It is suited for shop floor inspection stations and metrology labs alike. The battery-powered design makes it practical for locations where access to a fixed power outlet near the comparator is limited. It ships as a single unit and is used as a direct add-on to the comparator rather than as a standalone instrument.

Installation Notes

Installation and attachment of this illuminator accessory should be performed by a qualified metrologist or tool room technician familiar with the comparator model in use. Ensure the comparator is powered down or otherwise in a safe, stable condition before attaching or removing the illuminator. Refer to the comparator manufacturer documentation for proper mounting and alignment procedures. Do not force the attachment interface, as improper seating may affect optical alignment and measurement accuracy.
