1. Material characteristics

N-BK7 glass: a borosilicate crown glass with a transmission range of 350nm to 2.5 μ m, a refractive index of 1.5168 (@ 587.5618nm), high uniformity, and low bubble/impurity content.

Hexagonal design: Compared to square light guides, the hexagonal structure can reduce light loss by 35%, making it suitable for high-precision optical applications.

2. Product specifications

Size and parameters: Common models include apertures of 2nm, 4nm, 5nm, etc., with lengths ranging from 25mm to 100mm, and surface qualities of 60-40 or 40-20.

Performance: Suitable for visible light and near-infrared bands, some models are equipped with anti reflective films (such as 430-700nm or 1050-1700nm coatings) to improve transmittance.

3. Application scenarios

Laser beam shaping: used for spot homogenization and contour analysis of diode lasers.

OEM lighting: Optical modules integrated into industrial equipment such as medical instruments or testing devices.

Research field: Used in conjunction with high-precision optical systems such as spectrometers and interferometers.

4. Precautions

Selection suggestion: The length of the light guide tube should be selected based on the numerical aperture (NA) of the light source. High NA light sources are suitable for shorter pipes, while low NA light sources require longer pipes to achieve uniformity.

Maintenance: Avoid scratching with hard objects, and it is recommended to use specialized optical cleaning tools for cleaning.
