A surface plasmon resonance biosensor comprises: a prism, an incident light incident to a side of the prism and reflected at the side of the prism, the incident light comprising a first incident light having a first incident angle and a second incident light having a second incident angle, and a detector comprising pixels for detecting the incident light reflected at the side of the prism, where positions of pixels of the detector correspond to incident angles of the incident light, and where positions of pixels of the detector are calibrated by at least the first incident light having the first incident angle and the second incident light having the second incident angle.

Auto-calibration surface plasmon resonance biosensor

A disposable micro-prism test chip for surface plasmon resonance measurement comprises a micro-tray and a micro-prism mounted on the micro-tray. The micro-tray and the micro-prism form at least one cell for providing a fluid dielectric medium for measurement. The disposable micro-prism test chip also comprises a thin metal layer coated on the surface of the micro-prism in the formed cell between the fluid dielectric medium and the micro-prism. The micro-tray may have at least one through window for forming the at least one cell. The micro-tray may also have a half-through cavity facing the micro-prism. The disposable micro-prism test chip is disposed after at least one use. The micro-prism may be fabricated by pulling a heated preform, where the preform has the same cross-section as that of the pulled micro-prism.

Micro-prism test chip

A laser aligning device is mounted on the flat side of a putter grip or other cylindrically asymmetric surface of a club grip and emits a fan shaped light sheet. The light sheet is perpendicular to the flat side of the putter grip. The light sheet projects a visible laser line on a plane such as the ground when the head is on the same plane. The alignment of the grip relative to the putter head's face can be inspected by visually inspecting the orientation of the projected line on the plane relative to the head's face. The grip can be adjusted and fixed so that it is properly oriented to the face.

A training putter with a laser line projecting device can be used for putting training to improve putting skill. The device is affixed to a putter head above its sweet spot, and emits a vertical light fan which projects a line on the around normal to the face of the putter head. The line is aligned with the sweet spot of the putter head and lies on the ground to connect the top of a golf ball with a target, such as a cup or a putting hole, so that alignment can be easily visualized. The device can be detached and reattached easily without any laser alignment. Furthermore, the device can be removably mounted to a user's own putter. The heat generated in the laser diode is quickly dissipated through the metal housing, the metal putter head, and the metal shaft to the surrounding air. Since proper operating temperature of the laser diode can be maintained, the laser diode will operate properly, which means the power of the emitted light will not be decreased, and the lifetime of the diode will not be shortened.

Training putter with laser line projecting device

A method and apparatus for passively aligning microlenses and other optical elements and devices is disclosed herein. The method taught herein is particularly well suited to effect the passive alignment of cylindrical microlenses with other elements or devices, such as laser diodes. Cylindrical microlens structures formed in accordance with the principles of the present invention use a base substrate having one or more alignment sites. The alignment sites being formed using wafer scale fabrication techniques are formed with a high degree of precision, such that cylindrical microlenses fitted into the alignment sites are aligned with respect to each other and are positioned a proper optical distance from each other. These microlens structures can be constructed individually or constructed en masse enabling mass production of the microlens structures. Moreover, the microlens structures can be passively aligned with other optical elements. This can be effectuated by urging the optical element into intimate mechanical contact with an alignment member mounted on a microlens, thereby passively aligning the optical element with the microlens structure. This enables the fabrication of micro-optical devices using a minimum of skilled labor and achieving a superior degree of optical perfection.
