![]() | Making Raman Measurements Reproducible 28 Mar 2024 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. |
![]() | How to Select and Specify a Non-Linear Optical Crystal 01 Mar 2024 GAMDAN Optics 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. |
![]() | Manufacturing Considerations for Tolerancing Aspheres 10 Jan 2024 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. |
![]() | Measuring Aspheres in a 3D World 10 Jan 2024 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. |

![]() | 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. |
![]() | 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. |
