MidOpt LP Series – LP341 Protective Window
Uniforce Product
Salient Features
LP341 Industrial-Grade Oleophobic VIS A/R Coated Glass Protective Window
LP341 filters are similar to LP340 antireflection-coated protective windows except that they have the added advantage of an oleophobic coating on one side. They are offered in 1mm or 2mmm thickness. The oleophobic (anti-smudge) coating repels fingerprints, oils and moisture build-up, allowing for far easier cleaning. Frequent, uncontrolled rubbing during attempts to clean deposits or debris from the front surface of a lens will often cause scratching or pitting that results in loss of transmission and image clarity.
- Useful Range : 365-1100nm
- Cut-on Wavelength 50% T : 335nm
- Tolerance : +/- 10nm
- Peak Transmission : ≥98%
- Surface Quality : 40/20
Protective Filters are designed to shield your lens and lighting from dirt, dust, liquids, impact and harsh environments without sacrificing image quality.
- Economical solution to protect expensive lenses
- Useful for imaging in ultraviolet (UV), visible (VIS) and near-infrared (NIR) spectrums
- Available with a high-efficiency, anti-reflection coating to maximize transmission to 98% or more
- Offered in both glass and acrylic
- Exceptional surface quality; 40/20 scratch/dig
MidOpt StablEDGE™ optical filters are specifically designed to be less susceptible to effects from angular shifting seen when optical filters are placed in front of short focal length (<12 mm) camera lenses.
StablEDGE™ filters take advantage of absorptive filter glass to form the leading
edge of the filter passband.This assures no shifting in this region, even when the
lens FOV exceeds 100°.StablEDGE™ designs are less angle-of-incidence sensitive, inherently more rugged, and are environmentally stable.
MOUNT & SIZE OPTIONS: In-stock, ready-to-ship Protective Filters are available in Threaded Mounts, sizes M13.25 to M105; 25.4® C-Mount; Slip Mounts; or Unmounted. Custom shapes and sizes are available.
