Look to the skies

A telescope, described as one of the world’s newest, has been completed following a project undertaken by researchers to develop some very specialist optical filters

How Delta Optical Thin Film is Meeting the Miniaturisation and Manufacturing Requirements of Today’s Optical Filters for Next-Generation Point of Care Devices

This article is brought to you by: 

The Point of Care (PoC) device market is growing rapidly and not just because of the effects of the recent pandemic. These 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 minutes.

Designing miniaturised custom optical filters without compromising on optical output for fluorescence-based POC devices

Optical filters are a key component of any optical system. As the market for advanced imaging and diagnostic technologies continues to increase, there is a growing requirement for high-quality optical filters that are designed and manufactured to adhere to specific customer requirements. Delta Optical Thin Film is developing optical filters 
for next-generation Point-of-Care (PoC) devices.

Thin-film interference filters for lidar

This article is brought to you by: 

In order to keep up with the technology, LIDAR interference filters must be designed to maximize signal-to-noise ratios by reliably isolating the target LIDAR return signal. High performance LIDAR interference filters have greatly improved signal-to-noise ratios and reduced the need for multiple filtering techniques.
