Coatings that
decide the light.
By controlling the thickness and make-up of thin films, a coating sets how much light a surface transmits, reflects or polarises.
- AR
Anti-reflection
More light through, less reflected. Brighter, clearer images.
Lenses · windows · filters - MET
Metallic reflective
Aluminium and silver layers for high, broadband reflection.
Mirrors · beam splitters - HR
Dielectric mirror
Many thin layers that reflect chosen wavelengths very strongly.
Lasers · resonators - FLT
Filter
Pass the wavelengths you need and block or attenuate the rest.
Spectroscopy · microscopy - BS
Beam-splitter
Split one beam into two at a set ratio.
Interferometers · imaging - POL
Polarising
Separate or change the polarisation state of light.
Polarising microscopes · displays
From raw glass to λ/4.
Follow one lens through eight operations, from blank to boxed.
01/ 08
Raw glass / crystal
Optical glass or crystal blank: BK7-class, fused silica, sapphire, Ge, ZnSe, CaF₂ and more.
