This page is the map of the whole filter range; the detail pages below it go deep on one family each. The manufacturer's documented filter group lists narrowband filters, bandpass filters, long-pass filters, shortwave-pass filters, infrared filters, notch filters and neutral density filters, with dichroic mirrors grouped alongside them and IPL filters sold as a main product line in their own right. An optical filter manufacturer that carries the full family matters when a single instrument needs three of them at once — an excitation bandpass, a dichroic and an emission longpass, for example, all specified against the same wavelength plan.
Bandpass Filters
Pass one band, block the rest: multi-wavelength glass 365–940 nm and custom centre wavelengths.
Narrow Bandpass Filters
Tight bands for fluorescence and medical assays, including a documented 520 nm medical-test filter.
Longpass Filters
Block the short wavelengths, pass the long: documented custom range 680–1100 nm.
Shortpass Filters
The mirror image of longpass: pass short, block long — the documented shortwave-pass family.
Notch Filters
Reject one narrow line — typically a laser line — and pass everything around it.
Neutral Density Filters
Documented laser infrared colour-glass ND listings in the optical filter group.
IR Cut Filters
Documented for sport-camera applications, per the listing name.
Dichroic Mirrors
Wavelength-selective reflectors that split or combine beams by colour.
How the Families Divide the Work
Bandpass and narrowband filters select a band. Longpass and shortpass filters select a side of the spectrum, divided by a cut edge. Notch filters do the opposite of bandpass — they remove one narrow band and keep the rest. Neutral density filters select nothing at all, reducing intensity across the band. Dichroic mirrors combine selection with geometry, reflecting one band and transmitting another at an angle. The documented listings include a laser infrared optical colour glass bandpass and ND filter line, listed as a combined line, and a customised narrowband coating green bandpass filter whose listing names the coating and states no base material.
Documented application anchors keep the family honest: fluorescent narrowband coatings, an 850/940 nm narrow bandpass line for face recognition, an infrared transmitting filter for sensors, an IR cut filter listed for sport cameras, and IPL photonic hair-removal filters — the IPL line being a main product in the manufacturer's own headline range. If your instrument is on that list, the detail page for its filter family sets out that family's recorded range; if it is not, send the wavelength plan and the custom route applies.
Frequently Asked Questions
Which filter family do I need?
Match the job: select a band (bandpass), select a side (longpass/shortpass), remove a line (notch), reduce everything (ND), or split by colour at an angle (dichroic). The detail pages explain each with documented listings.
Are these optical filters or electronic filters?
Optical — components that filter light. Nothing on this page is a circuit component.
What are the minimum quantities?
Family-dependent: selected bandpass listings document 1 piece, most application filters 10 pieces. The longpass listing's documented minimum is unusually high and is confirmed per quotation — ask when you enquire.
