Pay attention to the contrast ratio. Generally, you want a higher contrast between colors so the higher the ratio, the better. A color contrast checker can help with this.

Beacon Femtosecond Optically Gated Fluorescence Kinetic Measurement System - request a quote  - pdf Beacon together with Trestles Ti:sapphire oscillator, second and third harmonic generators. Femtosecond optical gating (FOG) method gives best temporal resolution in light-induced fluorescence lifetime measurements. The resolution is determined by a temporal width of femtosecond optical gate pulse and doesn't depend on the detector response function. Sum frequency generation (also called upconversion) in nonlinear optical crystal is used as a gating method in the Beacon femtosecond fluorescence kinetic measurement system. We offer Beacon-DX for operation together with Ti: sapphire femtosecond oscillators and Beacon-DA for operation together with femtosecond amplified pulses.

Color contrast — which is the difference in color between two elements —  influences how well users read and navigate a website. For users with visual impairments, including low vision, cataracts, or color blindness, color contrast significantly influences their experience. The lower the contrast, the more difficult it can be for these individuals to navigate a page.

NARROW-BAND HOLOGRAPHIC FILTERS are intended for suppression of powerful beams in research and in engineering, in particular, in laser spectroscopy, and also for protection from blinding and damaging by laser radiation various photo receiver devices and operator's eyes.

Our color contrast checker measures the contrast between the background or foreground colors of a web page and other web elements to ensure they meet WCAG conformance standards.

Remember additional factors such  screen resolution, brightness levels, and device types also affect site readability. Test colors on various platforms to ensure they’re adjusted for optimal readability on different devices.

Here’s the bottom line: the more contrast you have between your text and UI elements and background colors, the more accessible it is for everyone.

Contrast ratio refers to how bright or dark colors appear on screens. The more scientific definition is that contrast is a ratio of the luminance of the brightest color to the darkest color that the system can produce. Contrast ratios range from 1 to 21 (written as 1:1 and 21:1). The first number, L1, refers to the relative luminance of light colors while L2 is the second number that refers to the relative luminance of dark colors.

A color scheme is a combination of hues that are implemented in specific design contexts, such as a site’s layout. Color plays an important role in making your content accessible to people with visual impairments. Web color accessibility in design considers your audience and any condition or disability they may have in perceiving pigmentation.

Use the color contrast checker above — just input the foreground and background colors of your site and the checker will automatically calculate the contrast level.

AOTF Infrared Spectrometer Del Mar Photonics offer a handheld infrared spectrometer based on the acousto-optic tunable filter (AOTF). This instrument is about the size and weight of a video camera, and can be battery operated. This unique, patented device is all solid-state with no moving parts. It has been sold for a wide variety of applications such as liquid fuel analysis, pharmaceutical analysis, gas monitoring and plastic analysis. Miniature AOTF infrared spectrometer uses a crystal of tellurium dioxide to scan the wavelength. Light from a light source enters the crystal, and is diffracted into specific wavelengths. These wavelengths are determined by the frequency of the electrical input to the crystal. Since there are no moving parts, the wavelength scanning can be extremely fast. In addition, specific wavelengths can be chosen by software according to the required algorithm, and therefore can be modified without changing the hardware. After the infrared radiation reflects off of the sample, it is converted into an electrical signal by the detector and analyzed by the computer. Del Mar Photonics is looking for international distributors for RAVEN - AOTF IR spectrometer for plastic identification and for variety of scientific and industrial collaborations to explore futher commercial potential of AOTF technology.

When it comes to creating an accessible website, color choice matters. Including accessible hues in your design palette will make your site more usable to people who may have vision impairment or low vision.

Del Mar Photonics offers new Trestles fs/CW laser system which can be easily switched from femtosecond mode to CW and back. Having both modes of operation in one system dramatically increase a number of applications that the laser can be used for, and makes it an ideal tool for scientific lab involved in multiple research projects. Kaelyn Leake is a PhD student in Electrical Engineering. She graduated from Sweet Briar College with a B.S. in Engineering Sciences and Physics. Her research interests include development of nanoscale optofluidic devices and their applications. Kaelyn is the recipient of a first-year QB3 Fellowship. In this video Kaelyn talks about her experimental research in nanoscale optofluidics to be done with Trestles LH laser.

WCAG requires web pages to have at least a contrast ratio of 4.5:1 for normal text and 3:1 for large text in order to comply with Level AA standards. Level AAA requires a contrast ratio of at least 7:1 for normal text and 4.5:1 for large text.

The Web Content Accessibility Guidelines (WCAG) outline various recommendations for color accessibility, including guidance for color contrast ratios, luminance, backgrounds, and color spacing in order to make a site more accessible to those with any type of vision deficiency. The following aspects of website color schemes can help you design with accessibility in mind.

Near IR viewers High performance infrared monocular viewers are designed to observe radiation emitted by infrared sources. They can be used to observe indirect radiation of IR LED's and diode lasers, Nd:YAG, Ti:Sapphire, Cr:Forsterite, dye lasers and other laser sources. IR viewers are ideal for applications involving the alignment of infrared laser beams and of optical components in near-infrared systems. Near IR viewers sensitive to laser radiation up to 2000 nm. The light weight, compact monocular may be used as a hand-held or facemask mounted for hands free operation.

A color contrast checker ensures web pages are accessible by determining whether they meet WCAG color contrast requirements.

Contrast is measured by calculating relative luminance which is the intensity of light emitted by certain colors. To calculate the ratio, the luminance of the lighter color is divided by the luminance of the darker color. This results in a value ranging from 1:1 (no contrast) to 21:1 (highest possible contrast).

A color contrast ratio determines how bright or dark colors appear on a screen. They can range from 1 to 21 (written as 1:1 and 21:1, respectively). The first number in the ratio indicates the relative luminance (or brightness) of the light colors, and the second represents the relative luminance of dark colors. WCAG recommends using 4.5:1 as the minimum ratio for text and interactive elements.

A color contrast checker is a tool that measures the contrast between website elements such as background, foreground, text, images, or documents to ensure it meets WCAG accessibility standards.

Choose color combinations by focusing on background colors, text and typeface colors, calls to action (CTAs), and buttons.

Unlike conventional interference filters, which are made by vacuum evaporation techniques, holographic filters are fabricated by recording interference patterns formed between two mutually coherent laser beams. Since all layers are recorded simultaneously within a thick stack, the optical density of the notch filter is high and its spectral bandwidth can be extremely narrow. Also, since the layering profile is sinusoidal instead of square wave, holographic notch filters are free from extraneous reflection bands and provide significantly higher laser damage thresholds.

It’s recommended organizations provide higher-contrast text and images where possible; however, Level AA is the required standard for website accessibility.
