The quality of a high definition lens is similar to the quality of a digital camera. The higher the pixel count, the higher the degree of resolution, resulting in crisp vision with unmatched depth and clarity.

He-Nelaserratio

Any visible laser with an output less than 1 mW of power. Warning label requirements - yellow caution label stating maximum output of 1 mW. Generally used as classroom lab lasers, supermarket scanners and laser pointers.  Class 3a Any visible laser with an output over 1 mW of power with a maximum output of 5 mW of power. Warning label requirements - red danger label stating maximum output of 5 mW. Also used as classroom lab lasers, in holography, laser pointers, leveling instruments, measuring devices and alignment equipment.  Class 3b Any laser with an output over 5 mW of power with a maximum output of 500 mW of power and all invisible lasers with an output up to 400 mW. Warning label requirements - red danger label stating maximum output. These lasers also require a key switch for operation and a 3.5-second delay when the laser is turned on. Used in many of the same applications as the Class IIIa when more power is required.  Class 4 Any laser with an output over 500 mW of power. Warning label requirements - red danger label stating maximum output. These lasers are primarily used in industrial applications such as tooling, machining, cutting and welding. Most medical laser applications also require these high-powered lasers.

This customized vision correction solves unique vision problems and provides wearers with superior clarity, and sharper, brighter eyesight, whether they are nearsighted, farsighted, or have a mild astigmatism. High definition lenses also enable patients to enjoy up to a 20 percent wider vision channel for both intermediate and near distances, making computer use and reading more comfortable and enjoyable.

CT Series lasers were specifically designed for use in education. They are not an engineering product or design being sold for educational purposes. From the initial concept, everything about the attractive, safe design was intended to interest students in technology. It includes safety features such as 110-VAC-to-low-voltage power adapters, tamper-resistant screws, impact-resistant acrylic enclosure, easily locatable bright red laser shutter, bright and very durable nickel-plated laser aperture, industry-standard electrical connections and tripod mount.

High definition lenses, also known as digital lenses, are now available. These advanced technology lenses offer a number of benefits over conventionally surfaced lenses. Unlike conventional lenses, HD lenses are manufactured using digital computer technology and diamond-cutting tools that allow the lenses’ surface to be customized to an individual’s eyes.

High definition lenses are ideal for all patients who want to experience the latest in lens technology, while those with high prescriptions and large amounts of astigmatism will experience the greatest wow factor.

Fresnel Lenses are a compromise between efficiency and image quality. High groove density allows higher quality images, while low groove density yields better ...

The IF HN05 is a basic helium-neon CDRH Class II-rated laser. It is useful in most educational curricula as a beginning tool for exploring/experimenting in laser and optical technology. It is the lowest powered and most economical laser we offer (.5 mW of laser power is adequate for most basic optical experiments as long as there is not bright light in the room.)

Any laser with an output over 500 mW of power. Warning label requirements - red danger label stating maximum output. These lasers are primarily used in industrial applications such as tooling, machining, cutting and welding. Most medical laser applications also require these high-powered lasers.

Industrial Fiber Optics' CT Series of lasers are the most popular line of lasers used in middle and high schools in the United States. Designed for education, and featuring a bright blue transparent enclosure, their attractive looks invite students to participate and explore in optical and laser technology while seeing the laser's internal "working" components. With a complete set of features and long warranty, it is a product that is hard to surpass.

Evaluation of the beam status on the μrad order is made possible by inserting a collimation checker in the optical axis, eliminating much of the time and ...
