Detail Information

The LAMBDA 750 is an instrument ideally suited for chemistry and material science applications, busy academic and industrial laboratories that perform measurement of liquids, gels, and solid materials and need flexibility of sampling along with high measurement performance. It is designed to provide the maximum sampling flexibility for tough samples in chemistry, biochemistry and materials science.

The system is ideal for a busy research or teaching laboratory, as accessories and detector modules can quickly and easily be interchanged to provide the optimum configuration for each measurement. For industrial applications, the design of the LAMBDA 750 and its accessories maximizes productivity through simple design which minimizes adjustment and maintains critical performance at the highest level.

All of our LAMBDA UV/Vis/NIR & UV/Vis Spectrophotometers offer features and accessories designed for maximum versatility delivering optimal performance and value:

  • Universal Reflectance Accessory (URA) - Snap-on module, changes angle automatically - A PerkinElmer exclusive!
  • Unmatched sample compartment size
  • Dual Sampling Compartments offer more options
  • Integrating spheres to 150mm
  • General Purpose Optical Bench (GPOB) handles a wide range of samples - including lenses and telescopes
  • Wide range of sampling modules requiring only seconds to change

Application Note

Measurement of Total Solar Reflectance of Paint Panels using PerkinElmer UV/Vis NIR Spectrophotometers and UV WinLab Software

Paint manufacturers are interested in the reflectivity of their products. This characteristic involves properties in both the visible region where color is important as well as extending into the Near Infrared (NIR) region where the properties of the paint with respect to solar radiation are important. In particular, the most important aspect is the degree of reflectivity.

To remove the halogen lamp follow the steps below:
  1. Switch off the spectrometer and unplug the line power cord.
  2. Remove the lamp compartment cover.
    Lift vertically from the handhold on the rear of the Lambda 650/850/950. Press down the catch and push the cover off backwards on a Lambda 800/900, or to the left on the other Lambda instruments.
  3. If necessary, remove the lamp baffle by loosening and removing the two screws on the top of the baffle and lifting the baffle vertically upward.
    NOTE: Instruments made prior to January 1, 1997 may have a different type of lamp baffle as shown in Figure 2. This is held in place with the same thumbscrew used to hold the lamp in place. Loosen the thumbscrew just enough to allow the lamp baffle to be removed.
  4. Remove the lamp assembly from the bracket by slackening the thumbscrew and pulling the lamp mount vertically upward.
    Save the thumbscrew, as it will be used with the replacement lamp assembly.
  5. Carefully pull the white ceramic connector from the rear of the halogen lamp.
  1. Unpack the new lamp assembly, taking care to hold it only by the metal mount to prevent fingerprints on the lamp window.
    Fingerprints on the lamp window cause hot spots during lamp operation, which can lead to premature lamp failure.
  2. Attach the thumbscrew to the back of the new lamp assembly.
    Make sure you leave enough room so that you can slide the thumbscrew onto the mounting bracket.
  3. Carefully push the white ceramic connector firmly onto the pins on the base of the lamp.
  4. Slide the new lamp assembly with the thumbscrew attached onto the mounting bracket as shown below.
    Make sure that the notch at the base of the lamp assembly fits securely over the alignment stud on the mounting bracket, so that the lamp mount is flush to the mounting bracket.
  5. If necessary, wipe the lamp window with a soft cloth moistened with alcohol to remove dirt.
    The dirt would otherwise be burned in when the lamp is hot.
  6. Replace the lamp baffle and secure it into place.
  7. Replace the lamp compartment cover and plug the line power cord into the spectrometer.
