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 may be available on request
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 dichroic mirror is designed to reflect a broad spectrum of ultraviolet and visible light from 350–790 nm while transmitting near-infrared wavelengths between 835–920 nm.

It is suitable for fluorescence imaging, beam separation, and optical sensing systems using UV, visible, or NIR light sources. It helps separate beams by wavelength, effectively reflecting shorter-wavelength excitation or illumination light while allowing a target near-infrared signal to pass through to the detector with high efficiency.

Key specifications:

Wavelength / main spec: Reflects 350–790 nm; Transmits 835–920 nm
Bandwidth / transition spec: Longpass dichroic transition between 790 nm and 835 nm
Transmission / blocking: T >90% (835–920 nm); R >99% (350–790 nm)
Format / custom option: Available in mounted (dia 12.5–25 mm) and unmounted (25x36 mm to 35x52 mm) formats

Product Faqs

A dichroic mirror separates light by wavelength. It is designed to reflect one wavelength range while transmitting another wavelength range.

For example, a dichroic mirror may reflect a laser wavelength while transmitting a visible alignment beam, fluorescence signal, or another laser wavelength. The exact function depends on the reflection band, transmission band, and angle of incidence.

Most dichroic mirrors are designed for a specified angle of incidence, commonly 45°, unless otherwise stated.

Yes. Dichroic mirrors are commonly used for laser beam combining and beam separation when the wavelengths are different enough and the reflection/transmission bands match the system requirement.

For example, one wavelength may be reflected at 45°, while another wavelength passes through the mirror. Before ordering, please confirm the laser wavelengths, AOI, beam size, and required reflection/transmission performance.
