Objectivelens magnification

Wavefront sensing and correction through Adaptive Optics (AO) instrumentation enables real-time reduction in image distortion caused by atmospheric turbulence. AO systems afford considerable enhancement of both signal-to-noise ratio and spatial resolution for ground-based observations of objects in space. Wavefront sensors record the rapid variation of a wavefront, providing critical inputs to AO control and wavefront correction systems. Wavefront sensing in the SWIR wavelength domain is becoming increasingly prevalent and effective.

Spectroscopy in the SWIR region can be used to characterise the optical and electronics properties of a wide range of novel engineering materials in the field of solar cells, quantum sources and nano-lasers, optical probes and functionalised molecules for biosensing (using the deeper probing properties of infrared photons in biological media), or Carbon Nanotubes and graphene-based nanostructures.

Be careful to buy a microscope with the magnification that you need. High-power does not necessarily mean it is better in quality. Many microscopes provide fuzzy images if the magnification is more than 1000x.

Imaging and accurately quantifying all detail is often key. In some environments, scenery can be over-illuminated or details can be hidden. In scientific imaging, it can be important to quantify signal over a huge range of intensities within a scene, without compromising measurement speed.

A telescope’s ability to spatially resolve astronomical objects is limited by the size of its primary mirror. Interferometry is a technique used to overcome this limitation by precisely combining light collected by an array of small telescopes to achieve the spatial resolving power (without the light collecting capability) equivalent to that of a telescope with a single primary mirror the size of the full array. This technique has a long history in radio astronomy and is increasingly being adopted at visible and infrared observatories to resolve binary stars, planetary systems, and stellar surface features (e.g. starspots). Interferometers need very precise phase matching of light collected across the array, which, owing to atmospheric turbulence, can only be achieved with very short (ms) exposure times. Atmospheric coherence times tend to be slightly longer at SWIR wavelengths, but the photon count per exposure can still be very low.

Andor’s SWIR camera series, now including First Light Imaging C-RED SWIR cameras, provide superb sensitivity and speed performance across the Short-Wave Infra-Red wavelength domain. Technologies include market-leading InGaAs and the unique single photon sensitive ‘e-APD MCT’ imaging innovation.
