MKS' Ophir® Business Unit Expands Series of Precisely Calibrated Integrating Spheres for Measuring Divergent and Collimated Beams

MKS Instruments, Inc. (NASDAQ: MKSI), a global provider of technologies that enable advanced processes and improve productivity, announces new additions to the Ophir® Integrating Sphere series of products.

Designed for measuring divergent and collimated light sources, such as laser diodes and LEDs, the Ophir Integrating Spheres are integrating sphere and photodiode sensor systems for measuring the optical power of divergent, narrowband light sources. The series includes three precisely calibrated spheres that measure powers from 20nW to as high as 30W.

+ The IS-1 is a 1-inch (25mm) sphere that measures powers from 20nW – 20mW for light sources from 0.35µm – 1.1µm.

+ The 3A-IS is a 1.57-inch (40mm) sphere that measures powers from 1W – 3W for light sources from 350nm – 1100nm.

+ The IS-6 is a 5.3-inch (135mm) sphere with 4-ports. It measures both high and low power divergent beams, from 20µW to 30W, for light sources from 0.2µm to 2.2µm

All three integrating spheres can measure beams with divergence up to ±40 degrees. Each is delivered as a calibrated unit with a photodiode detector. The IS-6 can be purchased with no detectors for use in the user's measurement setup or as a uniform light source.
