Cap / LID for Ultraviolet

OUTLINE

UV-LEDs have recently been attracting attention for sterilization applications. Yamamura Photonics offers caps and glass LIDs made by joining silica glasses and metal materials especially for deep ultraviolet (265 nm band) applications expected to suppress viruses and bacteria. We have a lineup of two types of products. One is a type that achieves hermetic sealing of elements by utilizing our core technology, "Glass to Metal Seal (GTMS)". The other is a type assembled using UV resistant resin developed by the parent company Nihon Yamamura Glass. Please choose which type according to the required characteristics.

FEATURES

Silica glasses with excellent UV transmittance

We use silica glasses as the window parts, which have excellent transmittance up to deep ultraviolet (UV-C).
Transmittance: T> 90% @ 265nm (with AR coat)
Cap / LID for UV-B

Two types of products

・Sealing glass type
This type achieves high hermeticity (1 x 10-9Pa・m3/s or less) because of the high gas barrier of sealing glass. However, due to restrictions on the product’s shape, we can only manufacture products with round window parts at present.

・Resin type
Compared to the sealing glass type, the hermeticity is slightly inferior (about 1 x 10-8Pa・m3/s or less, depending on the conditions). Nevertheless, it is possible to select a metal material with a difference in expansion coefficient from silica glass because they are joined with flexible resin. Also, the shapes of products can be chosen freely.
Other than those described above, a product in which resin is applied directly to the silica glass substrate and semi-cured without metal frames (named B stage processed product) is now under development.
