| | | Optimum Transmission Range: • 350 nm-2.0 [im Ideal Applications: • Optical imaging in the visible spectrum • Stable temperature environments NOTE: Esco can work with any commercially available glass type. If there is a specific glass that is more highly suited to your particular application, please contact Esco at 1 -800-922-ESCO (3726) to discuss the design details. | | |
| | | For all standard optical glass components, or when optical glass is generically requested for custom elements, Esco Products uses normal quality BK7, a high quality optical glass that is used whenever the additional benefits of fused silica are not required. Since BK7 performs well in all chemical tests, no special handling is required, thus reducing manufacturing costs. It is a relatively hard material with extremely low bubble and inclusion content. BK7 provides excellent transmittance throughout the visible and near infrared spectra and down to 350 nm in the ultraviolet. | | |
