Stock Availability

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
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

This SP700 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: 700 nm cut-off wavelength
  • Bandwidth / transition spec: See specification table for transition characteristics
  • Transmission / blocking: T >95%; OD5 blocking from 715-1080 nm
  • Format / custom option: Available in Dia 12.5mm to dia 25mm (mounted/unmounted), 60x60mm(unmounted); Custom sizes and mounting options available on request
SP700 Shortpass Filter - Microscopy and Projection

SP700 Shortpass Filter - Microscopy and Projection

Microscopy and Projection (Protecting Heat-Sensitive Samples)

Very bright lights used in medical microscopes or video projectors produce intense infrared radiation, which is essentially pure heat. If left unchecked, this heat can literally cook a delicate biological sample on a microscope slide or melt the plastic components inside a projector. This filter acts as a "heat shield" (often called a hot mirror), letting the useful bright light through while stopping the destructive heat.

Recommended light source:

  • Tungsten-Halogen lamps: These are heavily used in biology microscopes to illuminate cells. The advantage of using them with this filter is that you get the bright, continuous light needed to see tiny details without drying out or burning the live cells you are studying.
  • Xenon Arc lamps: These are incredibly bright, intense lights used in theater projectors and advanced science equipment. They produce a huge amount of heat. Using this filter allows you to harness the sun-like brightness of the Xenon bulb while safely reflecting the dangerous heat away from the equipment.

SP700 Shortpass Filter - Laser Safety Windows and Surgery

Laser Safety Windows and Surgery (Blocking Dangerous Lasers)

In industrial cutting, welding, or medical surgeries, powerful invisible lasers (like Nd:YAG lasers at 1064nm or diode lasers at 808nm) are used. Because these lasers are invisible, they are very dangerous to the human eye and to security cameras. This filter can be used as a viewing window. It completely completely blocks the dangerous invisible laser from escaping, while letting the operator safely see what is happening inside the machine in normal color.

Recommended light source:

  • Standard White Room Lighting (Fluorescent or LED): The primary advantage is that the filter lets almost 100% of this everyday light pass through. This allows the human operator or standard security camera to monitor the workspace clearly and naturally without the window looking heavily tinted or dark.
  • Visible Red Aiming Lasers (e.g., 650nm): Because the main cutting laser is invisible, operators often use a weak visible red laser to show where the machine is aiming. The advantage of this filter is that it allows the safe red aiming laser to pass right through to the viewer's eye, while aggressively blocking the dangerous invisible cutting laser.
