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.

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.

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

Altechna

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

Altechna

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.

Bitflow

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.

LASERSMART® Laser Safety Program 18 Apr 2023

Kentek

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.

Optical filters for fluorescence spectroscopy in Point of Care instrumentation 04 Apr 2023

Delta Optical Thin Films

Photo-luminescence is the phenomenon that a material emits light after having absorbed light. When the emission of light happens almost instantaneously (in nanoseconds) it is called fluorescence and when the emission decays over longer time (milliseconds) it is called phosphorescence. A material that exhibits fluorescence is called a fluorophore and such materials are used extensively in the analysis of biological materials.

What is a Cobot? Bridging the Gap Between Robots and Humans 14 Mar 2023

Knight Optical

As we reflect on history, we can observe numerous systems with resemblances to robots. In fact, some concepts of robotics and artificial intelligence (AI) are speculated to date back to ancient times. The resourceful Ancient Greeks, for instance, created sophisticated automated puppet theatres1 , while the Ancient Egyptians devised ingenious mechanical operating systems embodied in figurines2 . Fast-forwarding to the present era, significant progress has been made since the days of Ancient Greece and Egypt. Nevertheless, it is evident that the fundamental mechanics of some contemporary systems bear similarities to those of antiquity.

Advantages of sub 50 femtosecond pulses in multiphoton microscopy 09 Mar 2023

HÜBNER Photonics

One of the main advantages of using ultrafast femtosecond fiber lasers is the high peak power that they offer, which is a result of their ultra-short pulse duration. This high peak power makes these lasers ideal for a wide range of applications, including multiphoton microscopy. In this white paper we show that sub 50 fs pulse durations provide unprecedented multiphoton conversion efficiencies with intense peak powers.

Choosing a Portable Raman Spectrometer 03 Mar 2023
