Lasers
Optics with high laser-induced damage thresholds (LIDT), beam expanders, and precision steering mirrors for cutting, welding, and research.
In a high-power beam line the optic is the consumable. Absorption becomes heat, heat becomes distortion, and distortion closes the process window. SPEKTON selects substrates and coating recipes for laser-induced damage threshold first, then holds the surface figure that keeps the focal spot where the process needs it.
Where we're used
High-LIDT protective windows
Fused silica and sapphire windows that shield cutting and welding heads from spatter while surviving continuous kilowatt-class exposure.
Steering & folding mirrors
HR-coated mirrors with tight flatness tolerances for scanner heads and beam delivery arms, where a fraction of a wave of curvature shifts the focus.
Beam expander & shaping optics
Wedges, prisms and plane-parallel plates produced to strict parallelism for beam expanders, isolators and back-reflection control.
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.
- Optical & Optomechanical DesignOptomechanical athermalization across materials with different coefficients of thermal expansion (CTE), designed end to end in CAD and Zemax.
