Crystran Ltd specialises in the manufacture and supply of optical components. We manufacture high quality windows, lenses, prisms and specialist optics using a wide range materials, including calcium fluoride, barium fluoride, magnesium fluoride, zinc sulphide, zinc selenide, geranium, and many other exotic materials. Our products are used in ultraviolet, visible and infrared optical systems all over the world. A wide variety of windows, lenses, prisms and ATRs are available as standard products, but we also manufacture bespoke optical components for specialist applications. In fact, the very nature of the IR, UV and visible optics industry means that custom components form the bulk of our operations. Crystran draws upon the experience of its optical experts and utilises state-of-the-art technologies to deliver first class solutions in line with our customers' design requirements. Customised optics can be manufactured as prototypes and in larger quantities. Our reputation as a leading manufacturer of windows, lenses, and prisms extends to the four corners of the globe. The quality of our products has been the cornerstone of our success for many years, and we remain fully committed to the ongoing improvement in product and service standards. Our operations are constantly monitored to ISO 9001 standards to ensure quality is maintained. Crystran is also now accredited to the Environmental Standard ISO 14001:2004. We employ an expert team of sales staff that possess in-depth knowledge not only of the optical components themselves, but also of the chemistry and physics of materials and crystal growth. They can provide all the advice and guidance you need to indentify the right product for your application. Give them a call or send a fax or email, and they’ll get back to you immediately with a response to your query. One of the many reasons why customers keep coming back to Crystran is our flexible approach to manufacturing. Whether you need a single optic or a high volume manufacturing run, we’re always ready to accommodate your needs. Crystran works with a wide range of crystals and innovative glasses that are valued for their transmission properties. You can find out more about these in the short summaries below. More information can be found by visiting the Crystran website, where Pdf downloads are available detailing each and every material that we use. If you would like any further advice or guidance regarding Crystran and the products we offer, please do not hesitate to get in touch with our experts.
Lithium Fluoride is the material with the most extreme UVV transmission of all, and as such is used for specialised UV optics. It transmits very well into the VUV region.
Diamond is widely used for transmission windows and domes. It is available either as single crystal (Type IIa), natural, synthetic or as polycrystalline CVD film.
Single crystal diamond is selected into four forms:
Ia ~98% of natural yield (>100ppm Nitrogen - yellow)
Ib ~0.1% of natural yield (~100ppm Nitrogen)
IIa ~2% of natural yield (1ppm Nitrogen)
IIb - Synthetic only (100ppm boron for electronic applications)
Type IIa is the only type used for optical applications. Diamond features IR transmission with a range of absorptions in the mid-IR between 2.5 and 7 microns due to lattice resonances.
