OPTICAL COMPONENTS Metallized Plate Beamsplitters Spherical Lenses Cylindrical Lenses Lens Kits The thin metallic film acts as broadband partially transmitting mirror Substrates polished both sides to λ/10 Wedged substrates (for ghost suppression) are also available as standard Standard diameters from 25.4 to 100mm Achromatic Doublets Multi-Element Micro Optics Mirrors Prisms Substrates & Windows Beamsplitters Polarizers Filter & Apertures These beamsplitters provide a highly neutral reflectivity over the visible spectrum and are most useful for broadband or tunable wavelength applications. A separate coating, optimized for use at the near-IR diode wavelengths, is available. Specifications & Tolerances Surface flatness: λ/10 Surface quality: 40-20 Thickness: ±0.2mm Bevel: 0.2mmx45° typical Transmission: Tav = 33% ±5%, 400-700nm Reflectance: Tav= 33% ±5%, 750-850nm Diameter: +0, -0.2mm Parallelism: ≤5arcsec or 1° wedge Clear aperture: >90% diameter Material: BK7, grade A Wedge (optional): 1° Metallized Plate Beamsplitters Wavelength Range (nm) PART NUMBER ORDERING & TECHNICAL SUPPORT For a 1° wedged substrate append -W to the part number and add $25 to the price. Note: Wedged substrates are thicker. 187
