Nikon P2-CIA QL1X Lambda/4 plate (65463)

The Nikon P2-CIA QL1X Lambda/4 plate is a quarter-wave plate accessory designed for use with Nikon’s P2-CIA Coaxial Incident Light Illuminator on stereo microscopes such as the SMZ25 and SMZ18. This optical plate is used in polarized light microscopy to enhance contrast and reveal fine details in birefringent or reflective specimens. By introducing a precise phase shift between orthogonal components of polarized light, the plate enables advanced polarization techniques, such as observing interference colors and converting between linear and circular polarization. It is particularly valuable in materials science, geology, electronics, and quality control, where detailed surface analysis and optical property assessment are required.

This quarter-wave (λ/4) plate introduces a 90-degree phase shift between the ordinary and extraordinary rays in polarized light, allowing conversion between linearly and circularly polarized light.

Compatibility:
Designed for use with the Nikon P2-CIA Coaxial Incident Light Illuminator, and compatible with stereo microscopes like the SMZ25 and SMZ18, typically when using 1x objectives.

Key Features:

• Provides precise quarter-wavelength (λ/4) retardation, usually optimized for 550 nm (green light)

• Enhances the visibility of interference colors and allows analysis of optical path differences in birefringent materials

• Enables both qualitative and quantitative evaluation of optical properties such as retardation and orientation

• Useful for eliminating extinction bands and improving image clarity in the study of crystals, minerals, polymers, and other anisotropic samples

• Easily inserted at a 45-degree angle to the polarizer and analyzer for correct function

Applications:
Materials science for analyzing fibers, polymers, and crystalline structures
Geology and mineralogy for mineral identification and birefringence measurement
Electronics and semiconductor inspection for detailed surface analysis
Quality control and research involving advanced polarization techniques

This plate is an essential tool for anyone performing advanced polarization microscopy, providing precise control over the polarization state of light and supporting high-contrast, accurate imaging of a wide range of birefringent and reflective samples.
