Product Description

AR Coating: 700-1100nm
Attenuating low power lasers
OD: 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.3, 1.5, 2, 3, 4, 5, 6

LBTEK's Absorptive Neutral Density (ND) Filters with AR Coating of 700-1100nm have an optical density (OD) range of 0.1-6.0. The AR coating effectively reduces reflected light energy. LBTKE filters are available in a circular Ø25.4 mm size, with thickness varying depending on the material and optical density (OD). The Ø25.4 mm filters can be mounted in threaded tubes or installed on 30 mm coaxial mounting plates (OPM-12.5BS) for use in LBTEK's coaxial systems. We also offer other mounting options for optomechanical components. LBTEK provides customization services for filters with special sizes and optical density values.

Low-power applications
Absorptive neutral density filters
Anti-reflection coating: 700 nm-1100 nm

LBTEK absorptive neutral density filters utilize a Schott glass substrate with a stable absorptivity across the 700 nm-1100 nm wavelength range. This substrate is coated on one side with an Anti-reflection coating covering the 700 nm-1100 nm range. The coated surface serves as the incident surface, effectively reducing reflected light energy. LBTEK currently offers filters ranging from OD 0.1 to OD 6.0, all with a diameter of 25.4 mm. These filters can be mounted in LBTEK standard lens tubes, fixed lens mounts, and various coaxial mounting plates. Customers can select the optimal mounting method for their specific application. Note: The thickness of the absorptive neutral density filters is for reference only; the actual thickness depends on the optical density of the glass batch used.

Absorptive Neutral Density (ND) Filters, AR Coating: 700-1100nm, Mounted

Low Power Applications
Anti-Reflection Coating: 700 nm-1100 nm
Mounted in mechanical housing, detachable

The LBTEK absorptive neutral density filters have an optical density (OD) range of 0.1-6.0, with a size of 1 inch, and are coated with an anti-reflection coating for 700 nm-1100 nm. All MNDFA series absorptive neutral density filters come mounted in detachable standard lens tubes, with the surface engraved with product model, working wavelength, OD value, and other parameters for easy identification. The MNDFA series of absorptive neutral density attenuators are pre-installed in a removable standard lens sleeve. Parameters such as the product model, operating wavelength, and OD value are engraved on the surface for quick identification. Note: The thickness of the absorptive neutral density filter is for reference only. The actual thickness depends on the optical density of the batch of glass used.
