法国乔皮恩·依冯公司在1967年首次研制成了全息光栅,目前仍属领先地位。该公司的最新成果是制成了TV型凹面全息光栅。这种光栅不但球差小,而且彗差和象散降低到了最小程度。例如在该公司生产的H20和HL型单色仪及喇曼分光光度计上,均用了TV型凹面全息光栅。此外,还制成了面积达135×240mm,6500条线/mm的平面全息光栅,并正在研究用紫外激光器制造优质的全息光栅。
Giovann Evans, France, first developed a holographic grating in 1967 and is still a leader. The company’s latest product is made of a TV-type concave holographic grating. This grating not only small spherical aberration, and coma and astigmatism is reduced to a minimum. For example, the company produced H20 and HL monochromator and Raman spectrophotometer, are used in TV-type concave holographic grating. In addition, planar holographic gratings with an area of 135 × 240 mm and 6500 lines / mm have been made and high-quality holographic gratings manufactured by UV lasers are being studied.
