BK7 71x20x20 72x57x16 light guide block

    The N-BK7 homogenized cylindrical light guide tube is an optical component made of precision N-BK7 material, which converts non-uniform light sources into uniform light sources through the principle of internal total reflection. It is suitable for the visible light band (350-2200nm). Its hexagonal structure design can reduce light loss by 35%, which is superior to traditional square light guides.
DETAILS
 

core functionality

Uniform light source: adapted to non-uniform spectral characteristics of light sources.

Multi sided incidence: Supports six sided incidence, flexibly adapting to different lighting requirements.

OEM compatibility: can be directly integrated into customized lighting systems.


Selection suggestions

1. Numerical aperture (NA) matching

Light sources with low NA values should choose longer light guide tubes (such as 150mm).

Light sources with high NA values can be selected with shorter models (such as 25mm).

2. Application scenarios

Laboratory lighting: Recommended # 63-080 (50mm length, 2mm aperture).

Industrial testing: Optional # 49-404 (100mm length, 8mm aperture).


Other options

• fused silica light guide tube: suitable for higher temperature or UV band requirements.

• Dedicated interface: Simplify installation process and improve system stability.


Precautions

Cleaning and maintenance: Use a soft cleaning cloth and specialized cleaning agent to clean and avoid scratching the surface.

Storage environment: Store in a dry, well ventilated environment to prevent moisture and mold.

Usage: During use, avoid severe vibration and collision to avoid affecting its optical performance.
