'How To Order'

Standard Viewports

The standard range of viewports available through Laser Support Services Ltd., can be mounted on CF, ISO-KF & ISO-LF flanges, and employ 7056 Kodial glass as the window material. The window itself is sealed with a Kovar carrier which is subsequently welded into the host flange. Due to the Kovar alloy, standard viewports are magnetic. Standard viewports can be baked to a maximum of 400'C (depending upon host flange). Due to differing coefficients of thermal expansion of the materials used in construction, a maximum temperature gradient of 25'C per minute should be adhered to during heating and cooling.

Please contact us to discuss your requirements in detail or if you have any further questions.

Magnesium Fluoride Viewports

Magnesium Fluoride Viewports provide a wider transmission range than the standard viewports.

Please contact us to discuss your requirements in detail or if you have any further questions.

Sapphire Viewports

These viewports employ synthetic single crystal sapphire as the window material. Single crystal synthetic sapphire displays very different optical, physical and thermal characteristics depending upon the direction of the axis of the crystal structure. These viewports are offered as standard with the crystal axis at 90', i.e. parallel to the surface of the viewport. Viewports with 0' crystal orientation are available upon request.

Please contact us to discuss your requirements in detail or if you have any further questions.

Fused Silica Viewports

Fused silica view[ports offer increased transmission of UV and IR wavelengths. These are available in three grade types:

  • UV grade with window material HPFS fused silica standard grade

  • DUV grade with window material HPFS fused silica KrF grade

  • Excimer UV with window material HPFS fused silica ArF grade

A range of anti-reflection coated fused silica viewports which have an anti-reflective coating applied to both sides of the vacuum window achieving maximum transmission for various laser types.

Please contact us to discuss your requirements in detail or if you have any further questions.

Extended Range Viewports

A range of UHV viewports with extended transmission range materials are available through Laser Support Services Ltd. These are available in the following materials:

Calcium Fluoride

Magnesium Fluoride

Zinc Selenide

Anti-reflective coatings can also be applied if required.

Please contact us to discuss your requirements in detail or if you have any further questions.
