Dielectric Beam Splitter – 50/50 (R/T ~ 1)

50/50 Strahlteiler für Anwendungen im sichtbaren Spektralbereich (500–800 nm). Ideal für Laser- und Laboranwendungen mit stabilem Reflexions-/Transmissionsverhältnis bei 45° Einfallswinkel.

Designed for the 500–800 nm spectral range at 45° angle of incidence, this beam splitter provides a near-equal reflection/transmission ratio using a fully dielectric coating.

Key specifications:

• Reflection / Transmission: 50/50 ±2%
• Wavelength range: 500–800 nm
• Angle of incidence: 45°
• Coating: all-dielectric (low absorption, high durability)
• Substrate: BK7 (SCHOTT quality)
• Diameter: 25 mm

Applications:

• Interferometry
• Laser beam splitting
• Optical setups and experiments

Note:

Can also be used at normal incidence (see transmission graph in images).
