Large-diameter lenses and windows for cinema projection systems and high-resolution commercial imaging.
Projection and broadcast optics are judged by eye, at scale, on a screen metres across, so scatter, haze, and coating uniformity matter as much as raw transmission. SPEKTON produces large-diameter windows and flats with the cosmetic finish and coating consistency that cinema-grade imaging demands.
Where we're used
Large-diameter projection windows
Optical flats up to 500 mm with high cosmetic quality for laser projection systems, where any scatter shows up as veiling glare on screen.
Broadband AR coatings
VIS-NIR anti-reflective coatings applied with uniform spectral performance across the full aperture, so colour balance does not drift edge to centre.
Beam splitters & filters
Precision splitters and spectral filters for multi-channel projection and high-resolution commercial imaging chains.
Capabilities behind it
- Flat OpticsManufacturing to ISO 10110 standards for windows, mirrors, prisms, filters, and master flats requiring high flatness and sub-micron TTV precision, up to 500 mm diameter.
- Optical CoatingsIon-assisted deposition chambers, with a full spectral curve measured from VIS to LWIR for every batch.
- MetrologyA 100% quality control philosophy: 18 inch wide-aperture interferometry, 20 inch optical profilometry, CMM, and surface reference testing infrastructure.
