Precision Optics Capabilities

Centering:

LaCroix uses precision spindles and diamond wheels to accurately grind and bevel diameters in order to make optics concentric with their optical axis. This is done with 17 conventional and 4 high-precision CNC machines capable of diameter ranges from 3mm to 150mm.

Coating:

LaCroix uses resistively heated deposition, E beam deposition, ion assisted deposition, and plasma assisted deposition processes to apply broadband and ultra-broadband AR (anti-reflection) coatings for hot and cold mirrors, beam splitters, cut off filters, and other types of optical components.

Grinding and Polishing:

Grinding and polishing optics has been something that LaCroix Optical has been involved with since their inception. Using conventional and/or CNC methods, their staff is able to streamline the manufacturing for each part they work with, making it possible to produce more than one-million precision optics per year.

Metrology:

LaCroix Optical has invested in a large number of interferometers, spectrophotometers, spherometers, and micrometers in order to measure, verify, and document critical tolerances of complex optical components . Each device is regularly checked and calibrated in accordance with ISO 9001:2008 certification requirements.

Tooling:

LaCroix’s process support staff is comprised of manufacturing engineers and skilled machinists using CAD/CAM, CNC, and conventional machining equipment to provide the tooling required to quickly produce quality precision optics.
