Our visible optics portfolio spans the full 400–700 nm range, with substrate options including N-BK7, fused silica, borosilicate glass, and specialist optical glasses. All components are available with a wide range of anti-reflection, high-reflectance, and beamsplitter coatings optimised for specific wavelengths or broadband visible performance.

Visible Component Types

A comprehensive range of precision visible optical elements

Visible Lenses

Plano-convex, plano-concave, bi-convex, meniscus, and aspheric lenses in N-BK7 and fused silica. Available with broadband visible AR coatings or uncoated to specification.

Optical Windows & Flats

Precision-polished windows for imaging ports, instrument apertures, and protective covers. Supplied in N-BK7, fused silica, and borosilicate glass with surface flatness to λ/10.

Visible Mirrors

Protected silver, enhanced aluminium, and broadband dielectric mirrors for visible beam steering, cavity design, and imaging. Custom sizes, shapes, and radii of curvature available.

Beamsplitters

Plate and cube beamsplitters for visible laser lines including 405 nm, 488 nm, 514 nm, 532 nm, 633 nm, and 660 nm. Polarising (PBS) and non-polarising variants in stock and to order.

Prisms

Right-angle, Porro, Dove, Penta, and Amici prisms in N-BK7 and fused silica. Used in imaging systems, rangefinders, periscopes, and beam deviation applications.

Optical Filters

Bandpass, longpass, shortpass, neutral density, and notch filters for visible wavelength selection. Custom centre wavelengths, bandwidths, and OD levels available to order.

Diffraction Gratings

Ruled and holographic gratings for visible spectroscopy and wavelength-dispersive instruments. Optimised blaze angles for specific visible wavelength ranges.

Achromatic Doublets

Cemented achromatic doublets corrected for chromatic and spherical aberration across the visible spectrum. Ideal for broadband imaging, collimation, and focusing applications.

Substrate Materials

N-BK7 Borosilicate Glass350 – 2000 nmThe most widely used visible optical glass. Excellent transmission, low cost, and easy to polish to high surface quality. Ideal for general-purpose visible optics.
Synthetic Fused Silica150 – 2500 nmSuperior UV-to-NIR transmission, low thermal expansion, and high laser damage threshold. Preferred for laser applications and broadband instruments.
N-SF11 / N-SF57 Dense Flint400 – 2000 nmHigh refractive index glass used in achromatic doublets and prisms where strong dispersion correction is required.
Borosilicate (Pyrex-type)300 – 2500 nmLow thermal expansion glass for windows and substrates in thermally demanding environments. Good visible transmission and mechanical stability.
Sapphire (Al₂O₃)150 – 5500 nmExtremely hard and scratch-resistant. Used for protective windows and viewports in harsh environments requiring visible to mid-IR transmission.
