"First Contact" allows for cleaning optical surfaces without scratching by applying a liquid cleaner, letting it dry, and then peeling it off like a pack, effectively removing dirt such as oils and water spots. Unlike conventional wiping methods, it can also remove dirt from slightly uneven surfaces like grating. There is almost no residue left from the cleaner itself. Since the cleaner is inert to glass and metal, it can be stored while applied to prevent scratches and dirt on optical surfaces. 【Features】 ■ Apply the liquid cleaner and peel it off after drying for use ■ Capable of removing dirt from slightly uneven surfaces ■ Almost no residue from the cleaner itself ■ Inert to glass and metal ■ Can be stored while applied to prevent scratches and dirt on optical surfaces *For more details, please refer to the PDF document or feel free to contact us.

The "Wavelength Selector" allows for easy selection of the center wavelength and half-width. The center wavelength can be selected from 350nm to 900nm depending on the model, and the half-width can be selected from 2nm to 16nm. There are models that allow wavelength control via software and those that can be operated manually, enabling customers to choose a model based on their desired usability and wavelength range. In terms of specifications, it is highly efficient compared to standard bandpass filters. 【Features】 ■ Manufactured by SPECTROLIGHT Inc. in the USA ■ Easy selection of center wavelength and half-width ■ Center wavelength can be selected from 350nm to 900nm and half-width from 2nm to 16nm depending on the model ■ Customers can select a model based on their desired usability and wavelength range ■ Multiple center wavelengths can be selected with a single device *For more details, please refer to the PDF document or feel free to contact us.
