Two circular unmounted band pass optical filters overlapping on a reflective black surface, one showing a teal and cyan interference coating and the other a deep blue and purple coating, with colorful reflections beneath.

Band Pass

Two circular multi-band optical filters side by side — one large filter with a deep magenta and pink interference coating, and one smaller uncoated clear substrate, showing a mounted and unmounted configuration.

Multi Band

Two circular short pass optical filters overlapping at an angle, one with a dark olive-green coating and one with a vivid red-orange edge, illustrating the filter's spectral cutoff characteristics.

Short Pass

Two circular long pass optical filters — one upright showing a deep royal blue interference coating, and one lying flat with a soft lavender hue, both in unmounted form.

Long Pass

Two rectangular linear variable filter shown at an angle, displaying a continuous rainbow gradient from violet through blue, green, yellow, and red across its length, illustrating the spatially varying wavelength transmission.

Four unmounted optical filters arranged on a reflective black surface: a large circular filter with a deep magenta coating, a square filter with a purple-to-pink gradient, a rectangular linear variable filter displaying a full spectrum rainbow gradient from red through green to blue, and a small circular filter with an olive-green and yellow coating.

Available shapes - Square · Circular · Custom

Mounting Options - Beveled · Blackened edge · Mounted

Four circular unmounted optical filter substrates stood upright on a reflective surface, shown edge-on to highlight their varying thicknesses — ranging from very thin on the left to progressively thicker on the right. Each filter has a dark teal anti-reflection coating and casts a blue glow on the surface below.
