功能

• This holder converts the light emitted from the optical fiber of FC and SMA type connectors into a collimated beam with an objective lens.
• You can adjust the amount of beam divergence, the beam emission direction, and the center position of the beam brightness distribution (fiber rotation and tailgating).
• The use of a short focal length objective lens (OBL-10) provides collimated light with a small beam diameter.
• The microscope objective lens provides high transmittance and high performance (low spherical aberration) in the visible light range.
• Single-mode fibers provide a collimated beam with a Gaussian distribution.
• A dummy FC connector is included at the time of delivery. This connector cannot be used for fiber optics.
• * In the case of light input to a single-mode fiber, a precise adjustment mechanism is required.
• * Depending on the type of FC connector, it may be difficult to attach to the receptacle of the crosshair holder.
• * The collimated beam diameter depends on the NA of the fiber.
• * Generally, the beam diameter D is determined by the following formula.
• * D=2×NA×f f: focal length of the objective lens, NA: numerical aperture of the fiber
