This tool also functions as a basic API. Simply append &api to any permalink to get a JSON object with the contrast ratio and the AA/AAA pass/fail states. For example: https://webaim.org/resources/contrastchecker/?fcolor=0000FF&bcolor=EEEEEE&api.

Hint: Use the eye dropper tool in the Color Picker to extract the color value from any element on screen. Additionally, WAVE can analyze contrast ratios for all page text elements at once.

WCAG 2.0 level AA requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. WCAG 2.1 requires a contrast ratio of at least 3:1 for graphics and user interface components (such as form input borders). WCAG Level AAA requires a contrast ratio of at least 7:1 for normal text and 4.5:1 for large text.

The front lens of high-performance objectives is hand-polished by Nikon's most highly skilled experts (shown on right), a technique requiring more than a decade to master. By controlling the entire manufacturing process from glass formulation to assembly and alignment of lens elements, Nikon ensures the highest quality and performance of its objectives.

A miniature version of this Contrast Checker can be initiated within any web page by installing and using the Contrast Checker Bookmarklet. This tool allows easy contrast testing of any content on your screen by using the foreground and background eyedropper tools.

Zeiss objective

Optical glass starts as an ingot (shown on right) which is formed by blending rare earth elements and repeated melting, shaping and slow cooling to achieve a target refractive index. The glass ingots are precision-cut, polished and coated to produce lens elements for the objective.

Enter a foreground and background color in RGB hexadecimal format or choose a color using the Color Picker. Enter an Alpha value to adjust the transparency of the foreground color. Use the Lightness slider to adjust the perceived lightness of the color.

What does the objective lens do on amicroscope

Nikon has been developing optical glass since its inception in 1917, and to this day, wholly owns and formulates all of its glass.

Objective lenses are arguably the most important element in the microscope. Nikon has been developing optical technologies since 1917 with the establishment of Nippon Kogaku KK (Japan Optics). The JOICO microscope with interchangeable objectives and revolving nosepiece was first introduced in 1925. With over 100 years of dedication to the development of optics, Nikon continues to innovate and produce breakthrough optical technologies to help accelerate scientific research.

Nikon's online Objective Selector tool enables you to quickly and easily find the right objective for your application. Refine your search based on application, technique, objective class, immersion type, etc. Specifications for multiple objectives can be displayed in a single window for easy comparison.
