Improving Calibration Accuracy for High-End Spectroradiometers 06 Oct 2023


Admesy introduces a groundbreaking calibration concept that surpasses the limitations of conventional calibration light sources.

Imaging in Challenging Lighting Conditions — A Better Way 07 Sep 2023

Teledyne Lumenera

Choosing just the right camera for a particular application can be difficult. Common cameras specifications that are normally considered include resolution and frame rate. However, lighting is an external factor that is potentially even more important to consider. This document highlights how high conversion gain (HCG) and low conversion gain (LCG) camera capabilities can be beneficial in challenging lighting conditions, along with examples of imaging applications where these challenges commonly occur.

Making Raman Measurements Reproducible 28 Mar

Wasatch Photonics

Raman OEM applications need consistent spectra to deliver dependable answers. A good-quality OEM spectrometer should, by design, exhibit low unit-to-unit variability from the start, and any remaining small differences should be corrected in order to achieve the most robust and repeatable analytical outcomes in the field. Learn how to achieve >99.5% unit-to-unit agreement using a series of simple corrections.

UV Curing Adhesive Used in Electro-Optical Studies 07 Jun

Master Bond

Electro-optical (EO) polymers offer several advantages over inorganic materials in the fabrication of optical waveguide structures. Master Bond UV15 has been selected for use in the fabrication of polymer optical waveguides for a variety of applications. Read this case study to learn more about how UV15 helped the researchers achieve their goal.

Canadian InP quantum dot lasers: performance and applications 02 Jul

National Reseach Council of Canada

The National Research Council of Canada is developing and manufacturing quantum dots and dashes on GaAs and InP substrates for communications and quantum applications. Here we describe applications in the 1.55 µm wavelength range based on InAs quantum dots on the InP-based platform. We demonstrate lasers with significant performance advantages over conventional QW lasers when used in high-speed data communications applications.

How to Select and Specify a Non-Linear Optical Crystal 01 Mar


A key task faced by engineers using nonlinear crystals is the correct selection and effective specification of the appropriate NLO crystal for a particular laser design or application. GAMDAN Optics supports customers in successfully completing all the steps in this selection and specification process.

Measuring Aspheres in a 3D World 10 Jan

LaCroix Precision Optics

This white paper provides a practical guide on the benefits of 3D measurements of aspheres, featuring real-world case studies. This white paper also explains why one may prefer measuring aspheres in 3D over 2D, not to review the merits of the individual technologies as they apply to specific shapes.

Manufacturing Considerations for Tolerancing Aspheres 10 Jan

LaCroix Precision Optics

As aspheres become more prevalent in optical systems, it is important for lens designers to consider the various tolerances when designing an aspheric lens. Various topics discussed in this paper include irregularity and MSF errors (slope specification, maximum Zernike residual error, and spatial filtering), clear aperture, center thickness, and the dos and don’ts of tolerancing aspheres.

Anti-reflective coatings for infrared applications on IG6 substrates 11 Oct 2023


Chalcogenide glasses, due to their unique optical properties, open new prospects for infrared optics in various fields of industry and science. This paper presents a technology that has been developed to overcome the long-term problems associated with the adhesion of coatings to glass and contributes to the development of more durable coatings.

Quick Guide to the Selection of CW Laser Optics 17 Jul 2023


The maximum power of the continuous wave (CW) lasers on the market has been continuously growing, and has increased by almost a thousand times in just over a decade. Additionally, the beams of CW laser systems have been reduced in size due to the capability to use compact fiber lasers operating at kilowatt laser powers, without the need for additional sophisticated cooling. A major technological advance like this has created new production technology possibilities and permanently altered the industrial production techniques including cutting, drilling, welding, rust-cleaning, surface hardening, and other technologies employed in the Automotive, Aerospace, and Materials fields.

Next-Generation UV Mirrors 21 Jun 2023


Laser processing plays a critical role in both mass manufacturing and breakthrough innovations. Maximizing production efficiency and enabling future improvements requires application-tailored optical components, so Altechna has developed customized next-generation UV low-loss mirrors to meet these needs.

Controlling CoaXPress Cameras from The BitFlow SDK Tools, Configuration File and APIs 24 May 2023


The BitFlow SDK offers a number of different methods for programming CoaXPress cameras connected to BitFlow frame grabbers. The purpose of the this document is to explain how each method's components work together to provide camera control. There are a wide range of use-cases for this technology, so this document steps the reader through all the various workflows. Download the whitepaper here.

Unlike emCCD or sCMOS intensified cameras allow for photon detection down to 4ns. Photon Lines’ partner, Excelitas PCO explains this exciting part of their range 16 May 2023

Photon Lines / PCO

pco.dicam – a family of nine MCP image intensified camera systems offering extremely short exposure/shutter times. The choice of the photocathodes allows selection of spectral behaviour for different applications. Download the white paper here.

LASERSMART® Laser Safety Program 18 Apr 2023


A laser safety program based on ANSI Z136.1 “Safe Use of Lasers” standard is the cornerstone of any organization using Class 3B and 4 laser systems. Management is responsible for ensuring the safe use of lasers owned and operated under its control. The Laser Safety Officer (LSO) administers the overall laser safety program. This paper will mainly address Class 3B and 4 laser safety requirements and it will discuss the provisions of a laser safety program and personnel responsibilities.
