The realization of the final performance of the optical system depends not only on the
aberration correction of the optical design but more importantly on the control of the position …

This paper presents the validation of the design of a 6-in. f/2.2 dual-wavelength transmission
sphere (TS) based on the Fizeau interferometer. The TS was verified at a wavelength of …

We present a compact dual-view endoscope objective lens with a field of view (FOV) of±80°
and F/# of 3.4. The endoscope consists of two optical configurations for increasing FOV …

Aspheres and freeform surfaces are well measured with null optics but the transverse
coordinates on the test surface are not linear with the pixels on the imaging plane. Such a …

A design of high-precision 4-in. transmission spheres that can work in wide-band
interferometric measurement is proposed. A motorized precision rotation mount is used to …

We present a compact dual-view endoscope imaging system with a field of view (FOV)
of±80° and F/# of 3.4. The endoscope consists of two optical configurations for increasing …

The ideal mapping geometry in a Fizeau interferometer is to map equal height increments
on a flat object and equal angle increments on a spherical surface to equal heights on the …

The transmission sphere (TS) can only be used with a laser interferometer at a specific
wavelength. This paper proposes a design method that can make the TS work at multiple …

The transmission sphere (TS) provides a high-quality reference wavefront which is common
path with a test wavefront to generate interference fringes in a Fizeau interferometer. The …

The standard spherical lens plays an important role in the Fizeau interferometer. The
geometric characteristics and error analysis of standard spherical lens were reviewed. The …
