Yes. Listed filters are generally available from stock, but final availability may depend on size and quantity.

Most filters are kept as medium-sized coated pieces
Final size is usually diced before shipment
Preparation time may vary for urgent orders, custom sizes, or larger quantities

We can usually cut optical filters to custom outer sizes, depending on available coated material.

Custom size

Typical custom size range: 3 × 3mm to 60 × 60mm
Custom sizing changes the outer dimension only
Thickness normally follows the original filter specification
Final feasibility depends on coated material size and cutting requirements

Mounting

Standard mounting options are
dia12.5mm (mounted) - OD = dia12.5mm,Thickness=3.5mm,No Thread
dia25mm (mounted) - OD = dia25mm,Thickness=3.5mm,No Thread
Mounted options can include non-threaded or threaded mounts
Custom mounting may be possible depending on quantity and mechanical requirements

Note

Please send the required size, quantity, mounting type, and product link before ordering.

This SP830 shortpass filter is designed to transmit shorter wavelengths while reducing longer-wavelength infrared light. It is suitable for imaging, sensing, and optical inspection systems where shorter-wavelength signal needs to be separated from longer-wavelength background using broadband illumination or wavelength-centered signal detection setups. It helps reduce long-wavelength interference, protect detectors from unwanted infrared light, and improve signal clarity in shorter-wavelength measurements.

Key specifications:

Wavelength / main spec: 830 nm cut-off wavelength
Bandwidth / transition spec: See specification table for transition characteristics
Transmission / blocking: T >90%; OD5 blocking from 960-1200 nm
Format / custom option: Available in Dia 12.5mm to dia 25mm (mounted/unmounted), 60x60mm(unmounted); Custom sizes and mounting options available on request

SP830 Shortpass Filter - Industrial Laser Welding/Marking Inspection

Industrial Laser Welding/Marking Inspection

In manufacturing, cameras are used to watch machines weld or engrave metal in real-time. These machines often use powerful, invisible infrared lasers (like Nd:YAG lasers, which operate at 1064nm) to do the cutting. Without a filter, the intense invisible laser would blind or damage the camera. This filter shields the camera by blocking the dangerous 1064nm laser (which falls in the 960-1200nm blocking zone) while letting normal visible light through so the camera can clearly see the metal parts being worked on.

Recommended light source:

White LED Ring Lights: They provide bright, even, visible light that easily passes through the filter's 450-800nm window, allowing the camera to see the physical parts clearly without casting shadows or heating up the workspace.
Halogen Lamps: They offer a very natural, broad spectrum of visible light. This is highly advantageous if the camera needs to see highly accurate, true-to-life colors during the quality inspection process.

SP830 Shortpass Filter - Medical Laser Surgery Observation

Medical Laser Surgery Observation

During certain modern surgeries or dental procedures, doctors use high-powered infrared lasers to precisely cut or treat tissue. A camera is often attached to a medical microscope so the surgical team can watch on a monitor. This filter protects the camera sensor from being overwhelmed by the invisible surgical laser, ensuring the screen doesn't just show a massive blinding glare, while letting the visible colors of the tissue and blood pass through clearly.

Recommended light source:

Standard Surgical LED Lights: They produce brilliant, cool-temperature visible light that easily passes right through the filter, showing the true colors of human tissue without exposing the patient to extra heat.
Xenon Arc Lamps: Often used in fiber-optic medical tools (like endoscopes), they provide an extremely intense, pure white light that illuminates tiny, dark spaces perfectly for the camera to capture through the filter.
