Crystran has established itself as a manufacture of windows, lenses, prisms, ATRs and custom optical components in a broad range of materials including calcium fluoride, magnesium fluoride, barium fluoride, zinc selenide, zinc sulphide, germanium and many more exotic materials. It is also able to work with many glass types suitable for visible optics or near IR and UV. Crystran is presently able to offer a flatness of up to lambda/20 at 633nm in appropriate materials.

Delta Optical Thin Film will exhibit linear variable bandpass filters for mid-size and full-frame imaging sensors. The filters offer high transmission and are fully blocked in the light sensitive wavelength range of silicon-based detectors. They are ideal for creating hyperspectral imaging systems.

Edmund Optics will be showcasing a selection of optical components from its portfolio, including a new product, the Techspec YAG-BBAR coated achromatic lenses. The lenses consist of two optical components cemented together to form a doublet that is ideal for
Synthetic diamond manufacturer, Element Six, will be showing its Diamond PureOptics range. Drawing inspiration from the anti-reflective structure of a moth’s eye, this all- diamond solution offers improved reliability and higher power density levels for high power CO2
laser systems. Diamond optical windows typically
include an anti-reflective (AR) thin film coating to minimise reflection losses and maximise laser output power. However, these coatings have
mechanical and thermal properties far inferior to those of diamond, leading to increased thermal and mechanical failures as optical power densities increase. Element Six replaced these thin films with a diamond structured surface designed to reduce reflection losses. Diamond PureOptics exhibits significantly higher laser induced damage threshold (by a factor of

correcting on-axis spherical and chromatic aberrations. The achromats feature a broadband anti-reflective coating with transmission from 500- 1,100nm, and are optimised for less than 0.25 per cent absolute reflectivity at 532nm and 1,064nm. The lenses are designed to minimise the spot size for polychromatic illumination within the recommended usable wavelength range, but may also be used for focusing Nd:YAG lasers, especially those with an alignment beam. Custom manufacturing options are also available.
