The IDG has developed optical systems for ground-based and space-based instruments, from design through final testing. Our expertise spans wavelengths from the far-ultraviolet through the infrared.

Capabilites:

  • Optical system design
  • Precision component design
  • Ray trace analysis [ZEMAX]
  • Specification of fabrication and alignment tolerances
  • Production of detailed fabrication drawings
  • Management of component and system procurement
  • Assembly, alignment, and testing (including interferometry)
  • Metal and diamond-turned optics
  • Cryogenic and vacuum optical systems

Picture of NIR spectrograph Near-IR spectrograph for the Apache Point 3.5 m telescope
JHU is building a near-infrared spectrograph that will feature a highly efficient optical design. The IDG is leading the optical engineering effort for this instrument. [more]

The IDG played a key role in the development of the FUSE primary mirror assemblies, including: design, development of fabrication specs, fabrication oversight, integration, and testing. [more]

Picture of Offner relay Cryogenic Offner relay system for the IDTL
The IDG designed and built an all aluminum, cryogenic Offner relay for the Independent Detector Testing Laboratory. This image shows the rough blanks for the optics, prior to finish machining and diamond-turning. [more]

Picture of PRIME Imager PRIME Imager Module
The IDG designed the Imager Module for the Primordial Explorer (PRIME) mission. This module contains a corrector lens, three dichroic beamsplitters, and eight HgCdTe infrared focal plane arrays, all cooled to 74 K. [more]
