Enhanced Aluminium Front Surface Mirrors
Enhanced aluminium front surface mirrors are a go-to solution for visible applications, offering greater than 94% reflectance between 450 and 650 nm.
Stock Capabilities: We offer different flatness grades of enhanced aluminium front surface mirrors, including 1λ over 25 mm, 1/4λ over 90%, and general purpose for applications where flatness is not a requirement. Knight Optical offers different dimensions from 5 mm to large mirrors at 560×400 mm in size.
Custom Capabilities: We offer different dimensions to suit the requirement, including cutting down of sheets of enhanced aluminium mirrors to custom sizes with a quick turnaround.
Applications: Beam steering, optical inspection systems.

Absorptive Neutral Density Filter Glass
Absorptive neutral density (ND) filter glass controls light levels by absorbing a portion of the incoming beam within the material itself, rather than reflecting it away. The degree of attenuation is determined by material thickness, giving engineers a straightforward and reliable way to manage laser power or control light intensity in fluorescence spectroscopy setups.
This product is popular across imaging, scientific instrumentation, and laser sectors, wherever precise control of light levels is needed without introducing unwanted reflections into the optical path.
Stock Capabilities: We offer OD 0.05 to OD 4 @ 546 nm, with dimensions from 7 mm to 50 mm.
Custom Capabilities: We offer different filter glass materials and dimensions to suit specific applications.
Applications: Laser power attenuation, fluorescence spectroscopy.

Gorilla® Glass Windows
Gorilla® Glass is a chemically strengthened glass developed to withstand the kind of everyday mechanical stress that standard optical glass would not tolerate. Its scratch resistance and durability make it a natural choice for protective windows and display covers, particularly in environments where the window needs to be thin without sacrificing toughness.
Common application areas include automotive displays and consumer electronics, where protecting a screen or sensor without adding unnecessary bulk is a key design consideration.
Stock capabilities: 1.1 mm thick windows, 5 mm to 75 mm diameters, and up to 200 mm in length. All uncoated.
Custom capabilities: Custom dimensions, addition of coatings such as anti-reflection to reduce surface losses.
Applications: Protective window, display covers.
