Precision Fabrication

Surface flatness to λ/10, scratch-dig to 20/10, parallelism to 5 arc-seconds.

In-House Coating

Two Optorun systems and two vacuum chambers — no outsourcing, full design confidentiality.

Built to Spec

Every order made from your drawing and tolerances — from prototype to production.

Verified Quality

Zygo interferometer, spectral verification, 100% inspection on critical specs.

Product Portfolio

Six families of flat optical components

Each product can be supplied uncoated or with functional coatings tailored to your wavelength range, substrate, and application.

Optical Windows

Flat substrates for sensor protection, environment separation, and optical sealing. BK7, fused silica, and more.

MEDICAL · LASER PORTS · SENSORS

Optical Filters

Bandpass, longpass, shortpass, and notch filters with custom center wavelengths and bandwidths.

FLUORESCENCE · RAMAN · VISION

Mirrors

Flat mirrors for laser delivery, beam steering, and imaging. High-reflection coatings to spec.

LASERS · INTERFEROMETRY · SCAN

Beamsplitters

Plate beamsplitters with 50:50 and custom splitting ratios for measurement and diagnostics.

INTERFEROMETRY · SAMPLING

Polarizers

Linear polarizers with thin-film polarizing coatings for specific wavelength ranges.

POLARIZATION · LASER CONTROL

Wafers

Polished glass and fused-silica wafers for MEMS, sensor packaging, and downstream fabrication.

MEMS · SUBSTRATES · SENSORS
Our Core Differentiator

Coating done under one roof

Most small Chinese optics workshops outsource their coating, adding lead time and hiding quality issues. We run our coating chambers on the same floor as polishing and inspection.

That means tighter lead times, batch-to-batch consistency, and complete confidentiality of your design data.

  • ✓Anti-Reflection (AR) — single-wavelength & broadband
  • ✓High-Reflection (HR) — laser-line, custom AOI
  • ✓Beamsplitter (BS) — symmetric & asymmetric ratios
  • ✓Dichroic (DM) & bandpass filter coatings
  • ✓Polarizing coatings on custom substrates
