Beam Combiner

Beam Combiners are ideal for applications where diode lasers are being used for system alignment. Designed for used at 45 degree, they transmit the long wavelength beam and align it with the 90 degree reflected diode beam.

Reverse Beam Combiner

Reverse YAG Beam Combiner refers to an optic component used to transmit a short wavelength beam(eg. 650nm) at an angle of incidence of 45º while reflecting a long wavelength 1064nm.

Specifications
Diameter Tolerance	+0/-0.13mm
Thickness	±0.25mm
Side1	T>99%@650nm,45AOI
Side2	T>99%@650nm R>99%@1064nm,45AOI
Flatness	λ/2 @1064nm per 25mm dia

Part No.	Material	Diameter (inch)	Thickness (mm)
BCBK-1-3.5-1064R	BK7	1	3.5
BCBK-1-7-1064R	BK7	1	7
BCBK-2-6.35-1064R	BK7	2	6.35

Where,
• α is angle of incidence
• n is index of refraction
• t is thickness
• d is displacement of the material
For example: BCZ-1-3, d=1mm; BCBK-1-3, d=0.8mm
