Achromats

Achromats
  • Sizes from 3 mm to 150 mm
  • Surface accuracies up to λ / 20
  • Centration to seconds
  • In-house custom coatings

MATERIALS: Optical Glass • Fused Silica • Filter Glass


Achromats are a specialty at LaCroix. Consisting of two or more elements (usually crown and flint glass) bonded together to correct optical aberrations, thousands are manufactured each week for the medical, defense and other markets.

LaCroix manufacturing engineers will work with our production specialist to optimize the manufacturing process utilizing a combination of CNC and conventional manufacturing methods. Special proprietary alignment devices are used to ensure the optical axis of the elements can be maintained to within seconds.

In-House Coating

In-House Coating

Our ability to custom coat your optics in-house provides you with an all-inclusive optics manufacturing partner. This means we can personally ensure quality throughout and meet quicker turnaround times. LaCroix’s engineers can use a stock coating or create a custom coating to meet your specifications. From ARs and HRs to beamsplitters and cut-off filters, high-performance coatings deliver exceptional value. Deposition coating technologies include resistive heat, electron-beam, ion-assisted and plasmaassisted. Coatings can be deposited in a wide working range of 300 to 2100nm.

We conduct in-house environmental testing to ISO 9211-1:1994E, MIL-F-48616, MIL-O-13830A, MILC-675C, MIL-C-48497A and MIL-M-13508C specifications for, but not limited to: adhesion, abrasion, humidity, temperature and solubility. Laser damage testing is also available upon customer request.

Coating is not just an afterthought in our processes. We’ve invested heavily in the capacity to coat our optics to the same high standards that we grind, polish and measure them. LaCroix can do the entire job for you all in one place.
