the 150mm-aperture off-axis collimator is customized for an optics institute under chinese academy of sciences. the collimator system employs a newton reflective structure designed principally to truly simulate the optical characteristics of stars at infinity.
the determined effective focal length is 1.5m; the spectral range is 400nm~2500nm; the beam parallelism is less than 2.5″; the axial wave aberration rms≤λ/20 (λ = 632.8nm);
regulating mechanism: multi-dof fine adjustment is available.
