Product Family Description
- Excellent Transmission in 345 – 700nm Range
- Ideal for use with NUV LEDs and Mercury Lamps
- Low-Cost, Cemented Design
Our TECHSPEC® NUV Achromatic Lenses are specifically designed to minimize the spot size for polychromatic illumination in the 345 – 700nm region. Ideal for use in fluorescence applications, as well as for simple focusing of common UV light sources, such as Mercury Arc Lamps, UV LEDs, and Tripled Nd:YAG lasers. Our TECHSPEC® Near UV Achromatic Lenses feature a simple cemented design, and are an excellent alternative to air-spaced doublets and triplets for the UV. Lenses feature >90% transmission at 360nm and provide >50% transmission at 334nm.
