Spectrometer™

PC: 119521 (110v) • 219524 (220v)

 

The BPI® Spectrometer™ covers wavelengths from 350nm to 710nm with a resolution of better than 10nm. The transmittance spectrum results may be used for quality control purposes, such as comparing tinted lenses as well as providing information about what tints need to be added to match the color of another lens or a customer-supplied sample spectrum.
The unit is a free-standing complete spectrometer that can also be attached to a PC via the computer's USB port. The supplied software requires Microsoft™ Windows™ and PC. (Not included in purchase). The test results can be saved to an integrated database and also can be printed on any system printer.
The BPI® Spectrometer™ provides information on the visible transmittance (Tv) as well as the UVA transmittance of the material being tested along with the numerical color characteristics. (L*, a*, and b*). This provides a means for numerical color description. L*, a* and b* are the familiar CIELAB coordinates. L* is brightness (or lightness) ranging from 0 (black) to 100 (white). The a* value goes from about -80 (green) to +100 (red), while the b* value goes from about -80 (blue) to +100 (yellow). The PC software displays a transmission curve and allows one curve to be overlaid upon another.
BPI Spectrometers utilize a spectrometer chip (micro spectrometer mounted on a linear CCD detector array) to produce a survey type spectrometer with a resolution of about 10nm. The ‘entrance slit’ is a 300 micrometer optical fiber. The reflection grating has 625 lines/mm with a blaze wavelength of 560nm. The dispersion is 0.12nm/micrometer. The wavelength reproducibility is about 0.1nm. The ‘exit slit’ is a 256 pixel linear photodiode array. The visible light source is a high temperature incandescent bulb. The UV source is a UV LED.
Lenses must be removed from frame.

RGB Spectrometer™

PC: 19508 (110v) • 219523 (220v)

 

The BPI® RGB Spectrometer™ is a colorimeter:  a device that analyzes color and describes it in terms of  a mathematical model of  human vision.  It can be used by itself as a free-standing colorimeter, or it can be connected to the USB port of a PC (not  included).

Used by itself, the device reads the color of a lens or filter and displays its results in three systems: [1] RGB and Tv (measured relative to the internal light source and sensors);  [2] CIE XYZ coordinates referenced to a D65 source; and [3] CIELAB coordinates. For a bit more information on color coordinate spaces, see colorimetry.

In conjunction with a PC, the included software displays and can store for future reference the same information displayed on the meter itself, and it also provides a procedure by which an operator can correct the color of a dyed lens to make it match a standard lens more closely. A set of correction dyes is available whose characteristics are known to the software.

The correction process consists of measuring or retrieving the color of a standard lens and then repeating the cycle of measuring the sample lens, asking for a suggested correction, and then tinting the sample lens in corrector dye according to the suggestion.

  
Most lenses can be measured while in the frame.

BPI® is the world’s largest manufacturer of optical tints that are used by opticians, optometrists and ophthalmologists in tinting, dying, or otherwise coloring clear plastic – especially optical sunglass lenses. BPI® also produces lines of therapeutic tints providing UV protection and aiding with problems such as blepharospasms, headaches, retinitis pigmentosa, color blindness, corneal dystrophys, macular degeneration, retinal damage and dyslexia. BPI® has specialty tints such as EVA for viewing computer monitors and Solar Dyes for the finest sunglasses. BPI® also manufactures laboratory equipment such as tinting instruments, photometers, ultrasonic cleaners, edgers (for edging lenses), gradient lensors (for producing gradation of tint on lenses) and ovens for heat and chemical tempering of glass lenses for safety glasses and eyewear. BPI® supports all optical lens and sunglass manufacturers and optical laboratories.
