Protect your machine vision system with optical grade Acrylic windows

Posted on by Midopt Admin

MidOpt® offers a glass alternative filter line that is commonly used for potentially harsh environments, as well as food-safe inspection applications, such as those regulated by the Food & Drug Administration (FDA) and European Food Safety Authority (EFSA). These regulations prohibit glass in the inspection area. Acrylic windows are lightweight but impact resistant to provide a high-level of protection for your application while meeting these safety needs.

MidOpt offers a variety of high transmission (between 90-98%) acrylics that can be laser-cut to your precise specifications. These Acrylic windows are also available in threaded mounts from M22.5 to M105.

These MidOpt Acrylic windows have an Anti-Reflective coating that maximizes for maximum transmission, and the Oleophobic coating offered on the AC370 and AC400 prevents smudges and resists the buildup of oils and moisture and also helps aid cleaning.

MidOpt also offers Acrylic for Near-Infrared (NIR) applications, such as the AC760 and AC800, which passes only NIR light while blocking visible light. These filters are are well-suited for use with illumination in the 880nm and 940nm range. In addition, MidOpt also offers the AC900 and AC915 Acrylic filters for applications operating in Short-wave Infrared (SWIR).

New MidOpt LP8000 Germanium DLC Coated LWIR Protective Windows

Posted on by Midopt Admin

The MidOpt LP8000 Germanium Window has a DLC (diamond-like carbon) coating that is abrasion-resistant and can withstand harsh environments. It has a 7.5–12.5 micron useful range and is an ideal protective window for thermal camera enclosures. It also has an anti-reflection coating to maximize transmission when thermal imaging in the LWIR (long-wave infrared).  

The LP8000 has a very durable surface to withstand harsh environments and is designed to be resistant to corrosion, chemicals, alkalis and most acids.  It also serves to protect against abrasive airborne particles, salt water and high humidity.

Germanium is produced in single or poly crystalline form. It is a vital element used for semiconductors and IR optical components. Germanium is also widely used as a substrate in optical filters for manufacturing a versatile and very durable front optic.

Thermal Imaging Example

LP8000 features:

Like most MidOpt filters, the LP8000 is manufactured using StablEDGE™ Technology, making it far less susceptible to effects from angular shifting seen when optical filters are placed in front of short focal length (<12mm) camera lenses.

The LP8000 also comes with an Anti-reflection (A/R) coating. When a ray of light passes through a glass surface, a portion of the light is reflected, resulting in a 4% transmission loss per surface. MidOpt uses anti-reflection coating on all filter designs, reducing surface reflection to less than 1%. This improves the efficiency of the vision system by increasing transmission, enhancing contrast and eliminating ghost images. The LP8000 can also transmit wavelengths in the LWIR.

LP8000 applications:

  • Thermal Imaging
  • Medical
  • Automotive
  • Pyroelectric/Thermopile
  • Flame Detection
  • Defense & Space
