Our partner Glana Sensors have recently launched their first Hyperspectral Imaging camera that is capable of simultaneous 3D measurements. It is based on our Bifrost filters for Hyperspectral Imaging. Read more about the camera on Glana Sensors’ homepage and their brochure. The primary focus is on agricultural applications.

Fluorescence microscopy is a method of observing photo-emissive spectra from samples, and acquiring fluorescent signals that are roughly one million times weaker than the incident or one thousand times weaker than the scattered light. Observing the fluorescence of an analyte requires a sensitive array comprising an incident light source and robust optical filters with exacting […]
Hyperspectral imaging is the process of photographically acquiring data from across the electromagnetic spectrum, with the aim of obtaining spectral information in each pixel of a captured image. This detailed technique uses multiple imaging methodologies to photograph a scene across the spectral range in many contiguous spectral bands. Hyperspectral imaging spectrometers cover wavelengths beyond the […]
An optical bandpass filter is a spectrally selectively transparent component capable of transmitting select wavelengths of light while blocking others. They are fully customisable to varying center wavelengths and bandwidths, enabling their application in a broad range of practical applications including fluorescence spectroscopy, microscopy, and flow cytometry. Delta Optical Thin Film previously explored the range […]
Fluorescence spectroscopy is the processes of analyzing the emissive, spectral characteristics of a fluorescent compound which has been excited by photons of light. Typically, a sample will fluoresce light with longer wavelengths thus lower energy than that which it absorbed, requiring sensitive equipment with a broad wavelength range and high optical blocking (OD) to accurately […]
Fluorescence microscopy is a technique used to analyze biological structures in a sample using a white lamp, and either organic or inorganic fluorophores such as dyes to excite a photo-emissive reaction, which is observed using an optical bandpass filter and a dichroic mirror. Various biochemical industries rely on fluorescence microscopy for the performance of molecular […]
Laser raster microscopy, or confocal laser scanning microscopy (CLSM), is an optical analysis technique for fluorescence microscopy. It is a broadly applied image analysis method with applications in biological and medical research, and utilizes a combination of a diffraction-limited laser, beam splitters, and bandpass filters, to observe the excitation of photo-fluorescence particles, or fluorescent dyes […]
Fluorescence microscopy is an imaging technique that is often employed in medical research and biological applications. The technique uses fluorescence and phosphorescence in addition to, or instead of absorption or reflection to study the properties of a substance. Fluorescence microscopy is a popular technique as fluorescence has extremely high sensitivity and specificity, which helps to […]
Fluorescence is the phenomenon where a molecule absorbs light within its absorption band and then emits this light at longer wavelengths within its emission band. This phenomenon can be used to identify, quantify, and observe chemical activity, and it is a popular method due to its high levels of sensitivity, simplicity, and specificity. Fluorescence spectroscopy […]
