About
A 140 mm f/6.7 air-spaced apochromatic triplet combining super-low-dispersion and Lanthanum elements, hand-figured in-house on a Zygo interferometer to 0.96 Strehl or better, with the centre of correction moved toward the green where CMOS sensors are most sensitive. The lens sits in an adjustable, temperature-compensating steel cell; the all-aluminium tube is fully baffled and finished instrument white with a retracting dew shield. A test report is included.
