   Optical & Scientific Instruments

Hudson Research designs and manufactures a wide range of optical test instruments for research and production applications. These instruments are custom designed to meet the customers specific requirements. We offer three standard test instruments, the HRF-1 Production Interferometer, the UFT-1 Universal / Foucalt Tester, and the HRSP-1 Scanning Photometer. Hudson Research Inc is pleased to announce the next generation of Solid-State Polarization Instrumentation. These instruments all use proprietary electro-optical technology to replace cumbersome and unreliable mechanical components with compact high-speed electro-optic polarization devices. The Polarization Instrumentation product line will be available starting in the fourth quarter of 1998.

    HRF-1 Production Interferometer

    The HRF-1 Production Interferometer is a vertical format Fizeau Interferometer. It has a rapid test plate change capability, a built in camera port with integral electronic shutter, and easy adjustment to accommodate diffrent thickness parts. It is designed for production optical shops and allows readings in seconds on its built in display screen. Its camera port has a standard "T" mount for easy adaptation of film and CCD cameras. The HRF1 can be supplied with a small base for direct mounting on standard optical tables or with a larger base for free-standing application.

    UFT-1 Universal Foucalt Tester

    The Hudson Research UFT-1 Universal Foucalt Tester is a precision instrument designed to perform all classical optical bench tests. It incorporates a point source arc lamp with adjustable slit as its source, and has a precision knife edge in a rotary stage mount in its viewing system. The knife edge can be interchanged with a wire for additional versatility. The precision rotary stage permits highly accurate and repeatable measurement and determination of the various zones of the optical element under test. This instrument was originally developed for in-house testing of the IR telescope used in our Hyperspectral Imaging Spectroscope for the G-301 Space Shuttle Mission. It is incorporated in our 3 Meter optical bench. The instrument can be supplied with or without a bench and can be supplied with any standard optical bench mounting required.

    HIS-2 Hyperspectral Imaging Spectroscope:

    Hudson Research is pleased to offer the HIS-2 Hyperspectral Imaging Spectroscope as a commercial product. The HIS-2 represents the state-of-the-art in multispectral imaging systems. It is the first commercially available system to offer Sub-BLIP imaging with an uncooled temperature. The ability to image objects that are colder than an uncooled detector is unprecedented. The first Sub-BLIP images that demonstrates this capability are presented at this web site The instrument was originally designed for low earth orbit application, but its commercial version can be customized to suit the users needs. The general specifications (maximum values) are given in table 1 below.
