Custom Size & Mounting

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

This SP1165 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: 1165 nm cut-off wavelength
  • Bandwidth / transition spec: See specification table for transition characteristics
  • Transmission / blocking: T >90%; OD4 blocking from 1200-1800 nm
  • Format / custom option: Available in Dia 12.5mm to dia 25mm (mounted/unmounted), 60x60mm(unmounted); Custom sizes and mounting options available on request

SP1165 Shortpass Filter - Protection from SWIR Lasers (Laser Safety/Machine Vision)

Protection from SWIR Lasers (Laser Safety/Machine Vision)

This is likely the primary application. The blocking range (1200-1800nm) perfectly covers the common "Telecom" and "Eye-Safe" laser wavelengths:

  • 1310 nm (O-band telecom)
  • 1550 nm (C-band telecom, LiDAR, Rangefinders)
  • Application: If you have a machine vision camera inspecting a fiber optic component or a laser welding process, this filter allows the camera to see the part (illuminated by visible/NIR light) while completely blocking the blinding glare from the high-power 1310/1550nm laser.

Recommended Light Sources

  • 850nm or 940nm NIR LEDs: These wavelengths fall perfectly within the filter's high-transmission window (>90%) and match the peak sensitivity of standard Silicon sensors. This ensures bright, high-contrast inspection images while remaining completely distinct from the blocked SWIR (1310/1550nm) laser noise.
  • 630nm or 660nm Red LEDs: Located safely within the passband (starting at 595nm), these provide visible illumination which can be useful for manual alignment or operator verification, while still offering high transmission efficiency to the camera.

SP1165 Shortpass Filter - Optimizing Silicon Sensors (CMOS/CCD)

Optimizing Silicon Sensors (CMOS/CCD)

Standard Silicon sensors lose sensitivity rapidly after 1000nm and become transparent/noisy. However, strong SWIR radiation (heat or ambient IR) can still cause thermal noise or "ghosting" in the image.

  • Application: High-precision inspection in hot environments (e.g., glass or metal manufacturing) where you want to image the product using NIR light but block the longer thermal radiation wavelengths (1200nm+) that might wash out the contrast.

Recommended Light Sources

  • High-Power 850nm or 940nm LEDs: Maximizes Signal-to-Heat Ratio. These monochromatic sources emit light exactly where the silicon sensor is most sensitive and the filter is most transparent (>90% transmission). Crucially, because they do not emit "waste" energy in the SWIR band, they allow you to overpower the thermal background radiation of the hot object with a strong, active signal, ensuring high-contrast images without adding to the heat noise.
