Coatings & Precision Optics
From DUV to LWIR | AR/HR, filters, and PBS — specified to your wavelength and power, for lifetime.
Overview
Thin-film coatings and precision solutions for demanding optical applications.
We design, specify, and deliver thin-film coatings and precision optics from UV to FIR, through dedicated coating partners. You get filters, mirrors, polarization optics, and substrates that meet your specification — lot after lot.
Product Categories
Each category is shown with its engineering summary and representative application areas.
| Category | Summary | Application Areas |
|---|---|---|
| Optical Filters | We enable narrow-band, band-pass, edge, and notch filters from UV to FIR with steep edges and deep blocking — so your signal stands out from the noise, whether in a flow cytometer or a LiDAR receiver. | Biophotonics · LiDAR · |
| AR Coatings | Our AR coatings from UV to FIR deliver low reflectance — with laser damage thresholds specified to your actual power level, not a catalog number. | Laser optics · Imaging · Photonics Packaging |
| HR / Beamsplitter Coatings | We specify dielectric HR mirrors above 99.6%, protected metal reflectors, and beamsplitters with R/T held within ±2% — so your system's energy budget stays stable over its lifetime. | Laser Cavities · High-Power Laser · Interferometry |
| Polarization Optics | We specify PBS cubes, wire-grid polarizers, and waveplates with extinction ratios above 400:1 and retardation accuracy — because in polarization-sensitive systems, 'close enough' always shows up in the data. | Laser Polarization · AR/VR · Imaging · QT Applications |
| Precision Optics & Substrates | We supply prisms, lenses, windows, and micro-substrates — including TGV glass and wafer-level substrates — and coat them in one accountable flow, so interface problems have nowhere to hide. | Imaging · Spectroscopy · MEMS & Photonics Packaging |
| Custom Coating Services | Through our partner coating lines (IAD, sputtering, IBS, e-beam), we develop custom stacks from DUV to far-IR, qualify the process, and transfer it to pilot production. You get the coating; we manage the process risk. | R&D · High-Power Laser · Sensors |

Band-Pass Filters
Pass exactly the band you need, nothing more. Custom center wavelength and FWHM with steep transitions, tuned for biomedical imaging, machine vision, and detection channels.

Edge Filters (Long-Pass / Short-Pass)
A clean spectral knife-edge. Fast cut-on/cut-off transitions with high passband transmission and deep rejection — for spectral sorting, laser cleanup, and fluorescence separation.

Notch Filters
Remove one laser line, keep the rest of the spectrum. Narrow, deep rejection (OD 4+) with high transmission elsewhere — the standard cure for Raman and laser-line interference.
View DetailsOptical Coatings · AR Coatings
Single-Layer AR
The economical workhorse for single-wavelength or narrowband use. One layer, properly centered, still removes most of the reflection at a fraction of multilayer cost — ideal when volumes are high and specifications are forgiving.

Broadband AR (BBAR)
Broad, flat, low reflection across the full working band. Multi-layer designs hold R < 0.25% average over hundreds of nanometers, so imaging chains and sensor windows stay efficient without re-coating per wavelength.
View DetailsOptical Coatings · AR Coatings
Dual / Triple-Band AR
One optic, two or three laser lines. Discrete-band designs eliminate the need for multiple coated parts in multi-wavelength systems, simplifying alignment and BOM.

V-Coat (Narrowband HP-AR)
Engineered for a single laser wavelength where every ppm of loss matters. High-LIDT designs for intra-cavity and high-power applications, validated with damage-threshold testing.
View DetailsOptical Coatings · HR / Beamsplitter Coatings
Dielectric HR Mirrors
Maximum reflection where your system budget allows no leakage. All-dielectric stacks reach R > 99.8% at design wavelength with high damage threshold — well suited to laser cavities and high-power beam steering.

Metallic Mirrors (Au / Ag / Al)
Broad, tolerant reflection from UV to far-IR without angular sensitivity of dielectric stacks. Protected and enhanced metal coatings for IR systems, free-space optics, and medical lasers.

Plate Beamsplitters
Precise, stable R/T ratios on a simple plate. Broadband or narrowband designs hold ±2% tolerance for interferometers, imaging paths, and power-monitoring taps.

Cube Beamsplitters
Robust beamsplitting in a handled, alignment-friendly form. Cemented or air-spaced cubes with polarizing or non-polarizing coatings, built for instruments that ship and survive.

Wire-Grid PBS
High-contrast polarization on a wafer-level, thermally robust platform. Nanoscale metal gratings deliver stable extinction where film polarizers degrade — especially at high power and elevated temperature.

PBS Cubes
Classic polarization splitting in a rugged cube. High extinction and transmission for imaging, laser systems, and isolator cores, with proven cementing for long-term stability.

Polarizers (Linear / Circular)
Broadband linear and circular polarizers in the size and substrate your design needs. High extinction and transmission, cut and mounted to order.

Waveplates & Retarders (QWP / HWP / Achromatic)
Precise phase control from 400 nm to 2000 nm. Quartz and achromatic retarders at λ/300 accuracy, in custom apertures — the quiet enabler of telecom, polarization, and QT optics.

Lenses (Spherical / Aspheric)
Catalog-standard to custom spherical and aspheric lenses with verified figure and finish. Ready for collimation, imaging, and photonics packaging — coatings matched to your wavelength.

Micro Parts & TGV / Wafer Substrates
Micron-scale glass parts and through-glass-via substrates that bridge optics and electronics. Precision dicing, drilling, and metallization for MEMS, photonics integration, and wafer-level optics.
