Optical Systems Fabrication: Optical fabrication lies at the very heart of our operations and plays a vital role in maintaining our position as a world leader in the field in optics. Every step from grinding, polishing and coating through final testing utilizes the most advanced technologies and processes. Training of our opticians is performed through a four-year intensive program.

ELCAN technologies for Optical Fabrication include:

Diamond Point Turning (DPT): We are capable of performing the design, development, production, coating and testing of diamond-machined flat, spherical, aspherical and diffractive infrared optics and integrating these components into high performance cost-effective subsystems.

ELCAN is capable of machining a multitude of different polymers, crystals and non-ferrous metals. Some of the more commonly machined materials include Aluminum, Germanium, AMTIR, Zinc Selenide, Zinc Sulfide, Polycarbonates, Silicon and Calcium Fluoride. Typical Diamond-Machining tolerances are 80 Angstroms surface finish and ¼ wave surface form. ELCAN has recently developed a proprietary new method of smoothing diamond turned surfaces to visible quality RMS of 30 Angstroms. The ELCAN VQ mirror finishing process provides for highly cost-effective broadband optical reflective system performance.

MRF: Unmatched broadband performance on proven and affordable aluminum based optical systems. The extreme accuracy and computer-controlled stability of MRF (Magnetorheological Finishing) makes the fabrication and polishing of exceptionally precise spherical, aspheric and non-traditional freeform optical shapes possible. The combination of ELCAN VQ and MRF is a truly revolutionary, proprietary solution unique to ELCAN Optical Technologies.

Thin Film Coatings: The key to ELCAN's success in this sophisticated, complex technology is the design and manufacturing processes and support infrastructure (metrology, maintenance, information technology and quality control), which provide four shift operations with minimal engineering and supervisory intervention. Yields on coatings with 80 to 200 layers approach to levels of single layer films. ELCAN has the capabilities to utilize of 700 production-approved coatings.

Specifying an Optical Coating: Optical coatings generally fall into three main spectral regions: the ultraviolet (UV), the visible and near infrared (VIS-NIR) and the infrared (IR). The coating materials used differ depending on the wavelength region of operation, though some specialized coatings are multi-spectral. Different coating houses may specialize in some or all of the wavelength regions. Specifying an Optical Coating or pdf version.
