LAL: Laser Grade Visible Cemented Achromats

LAL: Laser Grade Visible Cemented Achromats

LAL: Laser Grade Visible Cemented Achromats

Laser grade cemented achromatic doublet for low/moderate-power; 415-700 nm. Specially designed for laser-beam manipulation and focusing at low to moderate power, these achromats are computer optimized for infinite conjugate ratio. These lenses are held to the tightest focal length and surface quality of all our cemented achromats, with minimal spherical aberration and coma at visible wavelengths.
  • Product Code: LAL
  • Optical Materials: N-BAK4 and N-SF10 (or equivalent)
  • Design Wavelengths: 486.1nm (blue), 589.0nm (yellow), and 656.3nm (red)
  • Clear Aperture (CA): ≥ 90% of central diameter
  • Surface Quality: 20-10 scratch-dig per MIL-PRF-13830b
  • Surface Irregularity: ƒ/Ø< 3.0: < λ/2 p-v over CA at 546.1nm
    ƒ/Ø ≥ 3.0: < λ/4 p-v over CA at 546.1nm
  • Paraxial Focal Length: ƒ±1% at 589.0nm
  • Diameter Tolerance: +0/-0.15mm
  • Center Thickness Tolerance: ±0.25mm
  • Chamfer: 0.25 - 0.50mm at max FW at 45° ±-15°
  • Centration: ≤ 3 arc minutes
  • Cement: Ultraviolet-cured synthetic polyester
  • Maximum Storage Temperature: 90°C (cement limitation)
  • Correct Orientation: The most steeply curved (shortest radius) surface should face the infinite conjugate
  • Anti-reflection Coating: Ravg ≤ 0.5% per surface, 415 – 700nm
