UV Filters, Glass filters for Blocking or Passing UV

JNS offers UV Control in numerous forms:

UV Filters from JNS Glass & Coatings are designed for precise UV Control. JNS offers numerous UV Filters for absorbing, reflecting and also passing UV.

Large format sheet size up to 48” x 68”
Any size custom optics including concave lenses
Bandpass filters for blocking or passing specific bandwidths
Custom substrates, thicknesses and sizes

UV rejection filters are designed to block all and any unwanted UV energy while transmitting the desired light. UV rejection coatings are used in medical instruments, imaging systems, outdoor displays, industrial equipment and many other OEM applications requiring specific control of the UV spectrum.

UV passing filters are designed to pass all or a portion of the UV spectrum while blocking visible light or other unwanted bandwidths. UV passing filers are most commonly used in curing applications, fluorescence microscopy and Blacklite Lamps.

Features

JNS offers both standard and custom coatings to manage UV light.

UV Blocking
UV blocking glass windows and lenses from JNS can reduce or eliminate overexposure to UV light in a wide variety of applications from machine vision to architectural lighting.

Large format UV blocking glass from JNS is used to protect art and other ink based valuables in museum displays.

Outdoor LCD screens such as digital signage and menu boards can deteriorate quickly with long exposure to UV. UV blocking glass from JNS can protect the LCD display from UV while simultaneously enhancing visible transmission and contrast.

UV Passing
UV Passing filters from JNS can be us to pass UV light while blocking visible and or NIR light

UV passing filters are often used in direct fluorescence imaging applications

JNS offers numerous optical bandpass filters for both reflective UV imaging and UV fluorescence imaging

390LP Series

415LP UV Blocking, Anti-Reflective Window

This UV Filter reflects the full UV spectrum, and will not solarize over time, effectively blocking most of the light emitted by 395nm and shorter wavelength UV LEDs
This UV filters can also be used as a protective window for lenses and is well suited for color imaging applications.
The substrate material for this UV Filter is Borofloat®, meaning this UV Filter can tolerate temperatures up to 500°C.
For more demanding (non-imaging) applications, this UV Filter is also available on drawn fused quartz sheet material (≤1000°C).
Useful range: 415-1100nm
Cut-on Wavelength 50% T: 415nm
Tolerance: +/-10nm
Peak Transmission: ≥95%
