Light guides

What are you looking for in Stock?

Knight Optical’s light guides are available in BK7 or equivalent, Sapphire and UV Fused Silica in an assortment of diameters and thicknesses. We currently do not hold stock of these products and instead offer an extensive custom service to meet the most stringent of specifications. We supply precision custom light guides to IPL and other cosmetic laser companies globally.

Light guides serve as the key element in cosmetic laser, or intense pulsed light (IPL) applications. IPL is a cosmetic application commonly used for the removal of unwanted hair. IPL applications make use of a variety of wavebands to target different chromophores. For this reason our custom light guides are available in a choice of materials and coatings to suit your waveband requirement.

Our custom BK7 or equivalent light guides offer high internal reflection to minimise the loss of transmitted light. BK7 or equivalent can offer over 90% transmission between 330 and 2000nm, which makes this material an excellent choice for IPL applications used to treat pigmentation, as the peak absorption of the human pigment melanin is 335nm. BK7 or equialent is also recommended for its high homogeneity and low bubble and inclusion content.

Our custom UV fused silica light guides also provide over 90% transmission at 335nm and work efficiently down to 185nm, making them an excellent alternative to BK7 or equivalent for pigmentation treatment. In addition, our custom fused silica light guides offer high thermal conductivity and an increased laser damage threshold, both of which are essential for cosmetic laser applications.

Knight Optical also provide custom sapphire light guides, a common alternative to BK7 and fused silica. Sapphire is an extremely hard material, which offers increased durability and resistance to damage. Sapphire also provides excellent transmission over the entire visible and SWIR range.

Knight Optical supply high quality custom light guides made to your exact specification. Our light guides are available in UV fused silica, BK7 or equivalent and sapphire for use in a variety of wavebands. Our highly skilled metrology and QA technicians are able to individually inspect and test each component to ensure it meets our exemplary quality standard.
