Diamond Like Carbon: Why Intlvac's Coatings & Systems are Best Positioned to Support the Booming IR Optics MarketAs the IR industry booms, more control, manufacturing power, and excellence is needed. The IR range was traditionally explored for military applications, but it has seen a marked shift toward accessibility for the mass market. It is a field that is...
Trusted Glass Measurements for Better Product DevelopmentThe PerkinElmerUL270 integrating sphere is a unique accessory that allows new accuracy to be achieved in the measurement of light-diffusing materials and adequately solves the various measurement problems involved in measuring transmittance and...
Multiband Optical Filters Are Telecom Networks' MultitaskersMultiband optical filters have long been used in applications such as fluorescence spectroscopy, astronomy, and 3D cinema, to name a few. Such filters not only supported the development of dual- and multibandpass filters for use in the backbone WDM...
PFG Optics Products and CapabilitiesAn overview of the products and capabilities PFG Optics possesses. PFG Precision Optics produces and extensive range of high precision spherical and flat optics, combined with a variety of durable long lifetime thin film coatings and opto-mechanical...
PFG Optics Standard and Best TolerancesA list of standard and best tolerances for PFG fabrication and AR coating.

Introduction to Optical ReplicationOptical replication is a method of re-producing a reflective surface with the identical surface figure and optical performance of a master part. This process facilitates low- to large-volume production of various optic shapes, such as concave and...
Curve Radii RepeatabilityThis paper quantifies Lattice Materials’ measurement methodology and manufacturing repeatability of a small diameter spherically generated silicon blank.
Multilayer Coating for Extreme Ultraviolet ExperimentsExtreme ultraviolet (EUV) multilayer coatings have been designed and fabricated for many kinds of experiments including high-order harmonics application. In this paper, we present recent results obtained with Ru/B4C, Mo/Si, Zr/Al-Si, SiC/Mg...
High-Volume, Cost-Effective Uniform Deposition for Flat and Curved Optical SurfacesTo achieve thin film uniformity on flat surfaces, nearly every conventional physical vapor deposition (PVD) method requires masking, complex motion, or both. For curved surfaces, none of these methods are capable of delivering similar uniformities,...
Fabricating Low Loss GeO2 Thin Films for Planar Waveguides Such as Photonic Integrated CircuitsHigh quality GeO2 thin films that exhibit low loss and low surface roughness were produced by Intlvac’s Nanochrome IV PARMS system, proving that ion assisted AC dual sputtering is an effective fabrication technique. This is highly applicable to...
Manufacturing Considerations for Tolerancing AspheresAs aspheres become more prevalent in optical systems, it is important for lens designers to consider the various tolerances when designing an aspheric lens. The following is provided from the manufacturer's perspective on important tolerances to...
IR Filters for Gas AnalysisThin film filters specially designed for infrared applications ranging from environmental monitoring, thermal imaging, medical, and power distribution. We offer high transmission, narrow and wide passbands, high rejection outside the passband, and...
Dispelling the Myths About Laminated FiltersThere is a common belief that there is no longer a need for traditional bandpass optical filters. While this may be true in some cases, not all laminated filters are created equal. In this paper we will illustrate the advantages and disadvantages of...
UV Bandpass Filters for SterilizationUV light at 222 nm is capable of sterilization without harming human skin, making it a safe and effective technology to combat bacteria and viruses, including COVID-19. Optical filters can be designed to transmit the desired UV frequency while...
LIGHTENING THE LOAD: How Photonics is Reducing our Environmental ImpactFour companies from the Luminate startup accelerator in Rochester, N.Y. are making major contributions to sustainability initiatives with emerging optics, photonics, and imaging (OPI) technologies. Their work is driving energy savings and better...
Mid-IR Dispersive MirrorsDispersive mirrors in Mid-IR (1 – 6 µm) range could finally substantially aid the combination of various bulk materials, such as semiconductors (Si, Ge, GaAs) and dielectrics (fluorides, sapphire, YAG) as the straightforward means to compensate...
Identifying Thermally Activated Delayed Fluorescence using a SpectrofluorometerTADF was first observed in 1924 by Francis Perrin. In 2012 it received a resurgence in attention when Professor Chihaya Adachi and colleagues at Kyushu University used the TADF mechanism to harvest triplet excitons in organic light emitting diodes...
Hybrid Gain Flattening Filters in Optical Fiber AmplifiersIridian Spectral Technologies has developed what is referred to as a Hybrid GFF, which combines the functionality of both a WDM and the GFF on one component. Specifically, a Hybrid GFF can block the pump laser from light in the range of...
Laser Marking and Coding Made EasyIn the packaging industry, new marks, codes and packaging material requirements are driving manufacturers to seek marking and coding solutions with flexible and adaptable performance. This guide features a complete marking and coding solution for...
What Are The Main Applications Of Optical Coating?We provide you with a detailed analysis and introduction to the application of Optical Coating in your daily life.
Building a DIY Atomic Force MicroscopeAtomic force microscopes (AFM) are often seen as out of reach for many scientists with limited budgets. But they are useful and versatile tools for characterizing surfaces, mapping out morphology, and studying the behavior of tiny structures that...
Solutions for Fiber Optic ApplicationsHigh temperature polymer coating and sheathing products protect and support the latest fiber optic technology.
5 Most Common Mistakes in Designing Precision Super Hard ComponentsOver nearly four decades, IRD has been manufacturing precision optical and non-optical components in super hard materials. Roughly 80% of the designs have benefited from IRD’s proprietary Design for Manufacturability (DFM) Review. During these...
