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.

Yes. You may request the transmission curve or related spectral data for engineering review.

This LPDM1005 longpass dichroic mirror is designed to reflect a broad spectrum of visible and near-infrared light from 520–985 nm while transmitting longer infrared wavelengths from 1025–1600 nm.

It is suitable for laser systems, infrared sensing, and fluorescence imaging using Nd:YAG, fiber laser, or telecom-band light sources. It helps separate beams by wavelength, effectively reflecting shorter-wavelength pump or excitation light while allowing a target infrared signal to pass through to the detector or measurement system with high efficiency.

Key specifications:

Wavelength / main spec: Reflects 520–985 nm; Transmits 1025–1600 nm
Bandwidth / transition spec: Longpass dichroic transition between 985 nm and 1025 nm
Transmission / blocking: T >90% (1025–1600 nm); R >99% (520–985 nm)
Format / custom option: Available in mounted (dia 12.5–25 mm) and unmounted (25x36 mm to 35x52 mm) formats
