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
    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

This LPDM602 longpass dichroic mirror is designed to reflect visible wavelengths from 450–595 nm while transmitting a broad band of red and near-infrared light from 610–1200 nm.

It is suitable for fluorescence imaging, beam combining, and optical sensing systems using blue, green, or yellow light sources. It helps separate beams by wavelength, effectively reflecting shorter-wavelength visible excitation while preserving high signal brightness for the transmitted infrared and long-wavelength visible light.

Key specifications:

  • Wavelength / main spec: Reflects 450–595 nm; Transmits 610–1200 nm
  • Bandwidth / transition spec: Longpass dichroic transition between 595 nm and 610 nm
  • Transmission / blocking: T >90% (610–1200 nm); R >99% (450–595 nm)
  • Format / custom option: Available in mounted (dia 12.5–25 mm) and unmounted (25x36 mm to 35x52 mm) formats

Product Faqs

What does a dichroic mirror do?

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.
What angle of incidence should I use?

Most dichroic mirrors are designed for a specified angle of incidence, commonly 45°, unless otherwise stated.
Can this dichroic mirror be used to combine or separate laser beams?

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.
