These thin film cube beamsplitters combine the excellent characteristics of the laser
polarizing beamsplitters previously described with the advantage of broadband
application. The polarizing film is fully protected within the cube making them durable and
convenient to use. Three wavebands have been chosen to cover most general
applications: 450-680 covers the visible spectrum and a wide selection of laser
wavelengths, 650-850 covers most visible range diode lasers and 1300-1600 covers most
telecommunications band diode lasers. Although these polarizers will work well over the
entire broadband specified they are manufactured to laser performance standards.
