Abnormalities in white blood cell count are indicative of a blood disorder. Measuring these abnormalities is imperative. However, the use of flow cytometry and other conventional methods to assess...

On-chip laser frequency combs are a promising technology for applications including environmental monitoring, optical computing, astronomy, and metrology. However, the inability to design an on-chip...

Researchers at Penn State developed a metalens that is large enough to be put into a telescope, and then they used the optic to image the moon's surface. The metalens, which the researchers used to...

After starlight enters the atmosphere, it passes through layers of turbulence that grant the light a twinkling or flickering effect when viewed from Earth. This turbulence also affects the quality of...

Piezo and voice-coil steering mirrors from Physik Instrumente LP are designed for free space optical communications. Piezoelectric tip/tilt mirrors and voice-coil-driven units keep laser beams...

The COSMOS™ camera from Teledyne Princeton Instruments Inc. is a 66-MP large-array device designed for astronomy applications. The deeply-cooled camera features LACera™ large-area...

The Boson+ CZ 14-75 camera module from Teledyne FLIR features a factory-integrated, high-performance, 14- to 75-mm continuous zoom lens to streamline the manufacturing supply chain. Used for...

Since their invention in the late 1960s, charge-coupled devices, also called CCDs, have found widespread use in imaging applications. Electronic cameras based on CCD technology are used in...

The optical materials selected for an optical system depend upon the application, the required system performance and the environment in which the system is to perform; thus the materials’...

Charged-injection device imagers are metal-oxide semiconductor (MOS) detectors that can be fabricated using PMOS, NMOS and CMOS integrated circuit technology, and may be configured as a...

Abbe Error — Linear off-axis errors introduced by angular deviations coupled to a moment arm at the point of interest on stage mounted devices (θ in Figure 1). The effect of Abbe error...

The term 'diffraction grating' often brings to mind a surface relief grating, with ruled lines and a delicate surface. A transmission grating, however, opens up many new options for the optical...

Space can be a harsh environment for optical coatings. Optimax has successfully provided antireflection (AR) coatings for a wide range of space applications. This paper outlines the results of...

This paper is ideal for those wanting an introductory guide to the various types of diffraction gratings and understanding their advantages and disadvantages as well as including some useful grating...

Information from the universe can be more than just a two-dimensional snapshot. These digital assets can be transformed to enable us to listen to, feel, or virtually move through cosmic objects....

Adaptive optics (AO) is a technology originally used for removing the blurring effect of atmospheric turbulence on images in ground-based telescopes. Since then, it has been become invaluable in...

Adaptive optics can be used to correct for instrument and sample aberrations or to dynamically shape the wavefront and point spread function (PSF) to create new possibilities or reduce instrument...

Additional questions and answers: Q: What is the power intensity for the adjusted supercontinuum Stokes laser? A: There are at least two PCF modules commonly used for supercontinuum...

In astronomy, the main lobe of an antenna pattern that has a small angular extent in two mutually perpendicular directions. Invisible in space, it would resemble a searchlight beam.

Pyramid error in optics refers to an aberration in the shape of an optical surface, particularly in the context of mirrors. It is a type of distortion that can occur when the surface of a mirror...

An apochromat, often referred to as an apochromatic lens or apochromatic objective, is a type of optical system designed to minimize chromatic aberration. Chromatic aberration occurs when different...

The Shack-Hartmann wavefront sensor is an optical device used for measuring the wavefront aberrations of an optical system. It is widely used in adaptive optics systems to correct distortions and...

As the demand for fluorides and other high expansion materials increases, it is important to understand the risks/challenges involved with these materials and how they affect various factors such as...

Optical coatings modify the reflectance, transmittance, and absorptive properties of optic substrates to make them much more efficient and functional. From an optical manufacturer's perspective,...

Capture More. Further. Faster. Balor sCMOS for Astronomy.

In this educational video, we'll discuss the distinctions between different optical imaging filters used in astronomy. You will learn about Kron and John filters, Gaia filters and Sloan filters, and...

An astronomical mirror is generally a mirror used instead of lenses in astronomical and space applications. It is not limited in size, does not absorb UV or IR radiation, and is usually made aspheric...
