Custom N-BK7 Cube Beam Splitter Prism Overview

Felix Glass Co., Limited manufactures custom N-BK7 cube beam splitter prisms for optical measuring instruments, laboratory test platforms, periscope imaging devices, and industrial optical systems. The original product direction is retained: precision polished N-BK7 glass, optional reflective or anti-reflection coating, and black matte side paint for stray-light control.

How the Cube Beam Splitter Prism Works

Two precision prism elements form a compact cube geometry. A specified internal reflective surface can divide or redirect incident light, while polished entrance and exit faces support controlled transmission. Black matte paint on selected sides can reduce unwanted reflections outside the intended optical path.

Beam Direction

Supports beam splitting, folding, or periscope-style optical routing according to the coating design.

Compact Alignment

Cube geometry can simplify mounting compared with separate angled optical elements.

Black Painted Sides and Coating Choices

Black matte edge treatment is intended to absorb stray light that reaches non-working faces. The treatment can be applied only where the assembly requires it, leaving designated optical surfaces clear or coated.

  • Reflective coating: reviewed for the requested splitting or turning function.
  • AR coating: specified by wavelength band, angle of incidence, and operating environment.
  • Uncoated faces: available when the optical design or budget does not call for a coating.

Desire: controlled production

Manufacturing Workflow for Custom Optical Prisms

  1. Requirement review: confirm drawings, optical path, coating, paint, quantity, and acceptance criteria.
  2. Material preparation: select N-BK7 stock suited to the geometry and production volume.
  3. Grinding and polishing: process faces and angles to the agreed dimensional and surface requirements.
  4. Coating and painting: apply specified optical coating and black matte treatment to defined areas.
  5. Inspection and packing: verify the agreed parameters and protect finished optical surfaces for shipment.
Desire: application matching

Applications in Measuring, Laboratory, and Periscope Systems

Optical Measuring Instruments

Routes or divides light inside metrology and alignment assemblies.

Laboratory Test Platforms

Supports configurable beam paths for experiments, prototypes, and optical benches.

Periscope Imaging Devices

Folds an optical path where the housing requires a compact viewing geometry.

Industrial Optical Detection

Fits machine inspection, sensing, and optical detection equipment built to a defined drawing.

Desire: supplier capability

Why Work With Felix Glass on a Custom Prism

Felix Glass Co., Limited supports drawing-based optical glass processing from sample evaluation through batch production. Engineering communication can cover glass selection, polish quality, angular tolerance, coatings, black paint, inspection scope, and protective packaging.

For US-market procurement, specifications are presented in practical engineering terms and reviewed against the final assembly rather than treated as a one-size-fits-all catalog item.

Buyer questions

FAQ About N-BK7 Cube Beam Splitter Prisms

Can the cube size be customized?

Yes. Size, shape, bevels, and tolerances can be reviewed from a drawing or reference sample.

Can only selected sides be black painted?

Yes. The paint boundary should be identified on the drawing so working optical faces remain clear.

Is AR coating available?

Yes. State the wavelength range, incidence angle, and performance target for coating review.

What surface quality is available?

The retained product specification lists 20/10, with 60/40 optional; final acceptance should be confirmed for the project.
