Hyperspectral Imaging for Cancer Detection

Hyperspectral imaging is used to collect and process images across the electromagnetic spectrum. The technique is a combination of spectroscopy and 2D or 3D imaging, and it is used to obtain the spectrum for each pixel in the image. Obtaining the spectrum enables hyperspectral imaging to be used for detecting processes, identifying materials, and finding […]

Ultra-Hard-Coated Optical Filters

Optical thin film filters are devices that are used to selectively transmit, or reflect different parts of the electromagnetic spectrum, and they are used for a range of different applications. Standard optical filters include longwave and shortwave pass filters, bandpass filters, and dichroic and polarization beamsplitters. What is an Optical Filter Coating? Optical thin film […]

Optical Bandpass Filters from Delta Optical Thin Film

An optical bandpass filter is an element that allows wavelengths within a certain range to pass through and blocks any wavelengths outside of that range. These filters are often used for fluorescence microscopy, imaging, and spectroscopy among other applications. The passband is the range of the spectrum that is allowed to pass through the bandpass […]

Optical Filters for OEM Customers

An Original Equipment Manufacturer (OEM) is a company that develops and build parts or equipment that another manufacturer markets. Delta Optical Thin Film focuses on developing high-performance optical filters specifically for OEM customers. What is an Optical Filter? An optical filter is a device that selectively transmits different wavelengths of light. In the past optical […]

Optical Filters for Fluorescence Techniques

The emission of light by a substance that has absorbed any kind of electromagnetic radiation is known as fluorescence. There is a range of analysis techniques that utilize the fluorescence phenomenon, and Delta Optical Thin Film supply a range of optical filters that can be used for these techniques. This blog post will discuss some […]

Optical Filters Used in Point of Care Instruments

Point of Care (PoC) instruments have various uses in medical diagnostics, including the detection of infectious diseases, testing haemoglobin levels and monitoring blood glucose levels. They are a popular choice for these types of tests as they only require a single drop of blood, saliva, or urine and can be performed by a GP within […]

Mini Spectrometer Components

Mini Spectrometer Components: Gratings A spectrometer measures wavelength dependent intensity of radiation over a part of the electromagnetic spectrum, and it works by passing a beam through a slit onto a grating and then measuring the intensity of the spatially dispersed radiation that reaches the detector. There are various types of spectrometers available, and mini […]
