Telescope Optics Custom FeaturesDFM Engineering delivers the assurance that only experience can provide. Every optical system is custom created to meet customers' specifications and optical requirements. In addition to telescopes, DFM Engineering has produced multiple modern scientific instruments requiring excellent optics, including satellite trackers, beam directors, lidar scanners, and heliostats.EXAMPLE:DFM has also created and manufactured the Prime Focus Instrument™ (PFI™).A PFI™ retrofitted to older telescopes can allow them to be re-purposed to perform wide field astronomy such as multi object photometry, super nova patrol, variable stars, planetary transits, occultations, orbital debris searches, asteroid searches, etc. With a PFI™ the FOV can be increased to 1° or more.

Mirror PolishingMirrors larger than 26" are manufactured within the DFM Engineering Optical Facility. The optical shop capabilities have included a variety of large mirror sizes with multiple 51" mirrors adhering to critical customer specifications.Since the quality of the mirror is directly related to the light gathering power and ability to resolve detail, DFM technicians take extreme care in the process of grinding, polishing, testing, and documenting, the product.Optics TestingThe optical facility is staffed with expert technicians that deliver large quality optics typically used in telescopes. All primary and secondary mirror finishes are tested at DFM so as to be within the proper range. Finish on the mirrors is typically 80/60 for the primary and 60/40 on the secondary.Mirror handling systems that are specifically designed to integrate into observatories to safely allow technicians to move, reinstall and collimate the optics are a significant feature of the complete customer satisfaction provided by DFM Engineering.  The mirror handling equipment often consists of hoists, mirror insertion tools, carts, crates, lift tables, slings, and fixtures.

Lighting has a very real effect on mood and alertness. This is particularly important in education, healthcare, office and retail environments, where lighting can sway overall performance. VividTune's tunable white solutions are expertly designed with these needs in mind, letting you easily adjust the color temperature of the light and its intensity.
