New ADVANTECH™ Line of Hard Coat Bandpass Filters

These state-of-the-art filters offer steep slopes, high light transmission, superior durability and long life for demanding applications, such as spectroscopy, fluorescence, imaging and sensing in the biomedical, machine vision and semiconductor industries.

ADVANTECH first surface bandpass filters provide transmission rates over 90% at wavelengths from 337-1200 nm. These hard coat filters are manufactured using a magnetron-sputtered hard oxide coating precisely deposited without any absorbing filter glass. This coating produces optical filters that are thinner and lighter weight while providing greater resistance to extreme temperatures, humidity, scratching and other environmental hazards. Additionally, hard oxide coatings are known to extend filter life to as long as 30 years. ADVANTECH hard coat filters are available in three standard sizes and mounted in an anodized aluminum ring.

ADVANTECH thin films can be customized and applied to a wide range of substrate materials to achieve deep blocking and high transmission for various application requirements. These optical filters are suitable for high-temperature applications. They provide a steep transition from a high, peak transmission to OD4 blocking. Available at all major laser lines and atomic absorption lines.
