Infrared sensing using nanocrystal toward on demand light matter coupling 06 May 2021

New Imaging Technology

Nanocrystals are semiconductor nanoparticles whose optical properties can be tuned from UV up to THz. They are used as sources of green and red light for displays, and also show exhibit promises to design low-cost infrared detectors. Coupling subwavelength optical resonators to nanocrystals film enables to design photodiodes that absorb 80% of incident light from thin (<150 nm) nanocrystal film. It thus becomes possible to overcome the constraints linked to the short diffusion lengths which result from transport by hopping within arrays of nanocrystals enabling high photoresponse detector operating in the SWIR range.

The Solution to Coating DLC on Chalcogenides 29 Apr 2021

EMF

Coating chalcogenides with DLC is notoriously challenging and requires specialized technical expertise to meet the high performance and durability demands of IR applications

5 Applications of Gratings 29 Apr 2021

Wasatch Photonics

Diffraction gratings that operate in transmission can be used for many different applications, providing high efficiency, low stray light, and a range of dispersion options from 150-5000 lines/mm and operating at wavelengths 300-2500 nm. They also enable more compact, lens-based designs. Here, we review the top 5 most popular applications we see at Wasatch Photonics, and how our VPH transmission gratings excel at each.

Realistic Optical System Tolerancing: A Practical Example 28 Jan 2021

Ruda-Cardinal

While lens design software can assist with tolerancing, complex and/or critical optical systems require expertise beyond the software’s basic functionality. We represent tolerancing of optical systems as close to reality as possible by utilizing the most advanced tolerancing tools both built into lens design software and of our own creation

Light engine operating lifetime Robustness, Reliability, Longevity in Maintenance-free lighting 11 Nov 2020

Estimates of the operational lifetimes of solid-state light sources ranging from 10,000–50,000 hours of light output are frequently cited in research and commercial publications. However these estimates are often derived from performance data for single light emitting diodes (LEDs) and are not necessarily representative of integrated light engines in typical working environments. This white paper provides operating lifetime estimates for Lumencor’s solid-state light engines based on analysis of service history data.
