   BURLEIGH WA-2500 (WA2500)   Description / Specification:    
BURLEIGH WA-2500 Wavemeter Jr Wavelength Meter

The Burleigh WA-2500 Wavemeter Jr is an instrument for wavelength measurement of CW laser sources that combines accuracy with ease of use. The accuracy is +/- 1 part in 10,000 over the full wavelength range. The primary application for Model WA-2500 is measurement of the wavelength or the frequency of tunable lasers that operate from 400 to 1800 nanometers, particularly dye lasers, Ti:Sapphire lasers and diode lasers. Two detectors are provided to cover this range with high sensitivity. The VIS detector is used for lasers operating from 400 to 1100 nanometers, and the IR detector for lasers that operate from 600 to 1800 nanometers. Specifications. Wavelength Range: 400 - 1800 nm. Accuracy: 1 part in 10,000, at 1000 nm: 0.1 nm (1 cm^-1). Display Resolution(Display resolution is adjusted automatically depending on the linewidth of the measured light.): 0.01 nm (0.1 cm^-1). Display Units: Nanometers or wavenumbers in vacuum or air. Display Update Period: Normal Mode; 0.2 seconds, Average Mode 2 seconds. Input Power (Input power requirement is specified as power out of the fiber and into the instrument. For a collimated beam with a diameter 2.5 mm, coupling into the standard beam receiver is usually greater than 30%.): 20 microwatts. Beam Receiver Accessory: Coupling Head Aperture; 2.5 millimeter, Patch cord Cable Length; 3 meters. RS-232 Interface Standard (2400 Baud).

*This is a Web introductory price for one calibration of the BURLEIGH WA-2500. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Absolute Wavelength Accuracy
Absolute Wavelength Accuracy is the maximum difference between the actual wavelength and the displayed wavelength of the Optical Source. Wavelength is defined as wavelength in vacuum.

Decibel (dB)
A unit of measurement of optical power which indicates relative power. A -10 dB means a reduction in power by 10 times, -20 dB means another 10 times or 100 times overall, -30 means another 10 times or 1000 times overall and so on.

Nanometer (nm)
A unit of measure used to measure wavelength of light, meaning one one-billionth of a meter

Relative Intensity Noise (RIN)
Relative intensity noise (RIN), describes the instability in the power level of a laser. The noise term is important to describe lasers used in fiber-optic communication and LIDAR remote sensing. It is the square of the (spectrally resolved) RMS optical power amplitude divided by the measurement bandwidth and the square of the average optical power, expressed in dB/Hz.

Total Return loss
In an optical fiber, the loss that takes place at any discontinuity of refractive index, especially at an air-glass interface such as a fiber endface, at which a fraction of the optical signal is reflected back toward the source. RL = - 10log10 (Preflected/Preference)
