Astronomical Imaging

Image rotation prisms are used in astronomical imaging systems to correct or manipulate the orientation of images produced by telescopes, which often invert or rotate views due to their optical configurations. Prism designs such as Amici roof, Dove, Schmidt, and half-penta prisms allow astronomers to rotate, invert, or revert images while maintaining optical alignment for cameras, spectrographs, and other instruments.

Polarization optics control the orientation of light’s electric field, providing powerful capabilities for a variety of applications. By using components such as polarizers and waveplates to manipulate and measure polarization states, these systems can enhance contrast, reduce glare, and reveal information not accessible through intensity or wavelength alone.

Astronomy Bandpass Filters isolate and measure specific wavelength bands of light emitted by astronomical and celestial objects. Johnson–Bessel filters are commonly used with photomultiplier tubes, while Kron–Cousins filters are well suited for use with silicon-based sensors due to their spectral responsivity.

The RKE® line of eyepieces stands out as an industry favorite, known for its long eye relief and an apparent field of view of 45°. To help our customers take full advantage of advanced optical design software, we are pleased to provide complete prescription data for these eyepieces.

Precision parabolic mirrors are used in telescope systems to focus parallel starlight to a single point without spherical aberration, enabling efficient collection of faint light and sharp astronomical images. TECHSPEC® Precision Parabolic Mirrors offer high surface accuracy and multiple coating options, making them well suited for high-performance astronomical observation and optical system design.

Large precision achromatic lenses are used in astronomical imaging systems to reduce chromatic aberration by bringing multiple wavelengths of light to the same focal point. This correction improves image sharpness and color accuracy in refracting telescopes and high-resolution imaging systems.

Near-infrared (NIR) aspheric lenses are used in astronomical imaging systems to efficiently focus infrared wavelengths while chromatic aberrations. Their aspheric surfaces improve image quality and light collection efficiency, making them well suited for infrared astronomy, spectroscopy, and low-light detection applications.
