Laser Manufacturers

Optics & crystals for the laser sources you build

Vertically integrated optics, crystals and electro-optics for OEM laser builds — from first prototype to qualified serial supply, all manufactured and tested in-house.

Explore Laser Manufacturers Applications
Medical & Life Sciences

Optics for medical lasers and bio-imaging

Crystals, electro-optics and precision optics for medical laser OEMs — ISO 9001 traceability and consistent serial quality from prototype batch to dedicated OEM line.

Explore Medical & Life Sciences Applications
Semiconductor

Optics for lithography, inspection and processing

High-LIDT UV and DUV optics, harmonic crystals and beam delivery lenses for semiconductor laser tools — low-absorption coatings from 190 nm with full in-house traceability.

Explore Semiconductor Applications
Industrial

Optics that survive high-power environments

Protective windows, F-theta lenses and high-power mirrors with extreme-LIDT coatings — built for continuous industrial duty, from single replacements to volume OEM supply.

Explore Industrial Applications
Laser Fusion

Large-aperture, high-damage-threshold optics

Large-aperture conversion crystals, Pockels cells and damage-resistant transport optics for MJ/PW-class beamlines — coatings up to ø1100 mm, LIDT beyond 100 J/cm².

Explore Laser Fusion Applications
Scientific & Research

Precision optics for labs and institutes

One of the broadest crystal and optics catalogs in photonics, plus fast custom manufacturing — from a single specialty crystal to complete lab infrastructure.

From an R&D Project to a Full OEM Program

Define the target — wavelength, coating, damage threshold, tolerances — and we take it from design and prototype to full serial production in-house, scaling the same part from a single R&D piece to OEM volumes.

  1. 1

    Specify

    Share your target spec, expectation, or just the problem. Speak directly to one of our engineers.

  2. 2

    Design & quote

    We propose substrate, coating and tolerances with a costed, manufacturable design.

  3. 3

    Prototype

    In-house cutting, polishing and coating with full interferometric QC and certs.

  4. 4

    Serial OEM supply

    Repeatable, traceable production scaled to your volumes and schedule.
