摘要	An embodiment of a light delivery portion of a photoplethysmographic device having a series of two or more optical elements. The series of two or more optical elements (20, 40, 50) are arranged to conduct light (10) from a laser and at least two consecutive elements of the series of two or more optical elements are coupled together by a non-reflective coupling (30a, 30b). This minimizes the extent to which back reflected light can re-enter the laser and adversely alter the optical output properties of the laser and additionally minimizes the light loss associated with back reflection thus helping to maximize the optical throughput. Other embodiments are described and shown.
其他摘要	光电容积脉搏波描记装置的光传输部分的实施方案，其具有一系列两个或更多个光学元件。一系列两个或更多个光学元件（20,40,50）布置成从激光器传导光（10），并且一系列两个或更多个光学元件中的至少两个连续元件通过非反射耦合耦合在一起（30a，30b）。这最小化了背反射光可以重新进入激光器并且不利地改变激光器的光输出特性的程度，并且另外最小化与背反射相关的光损失，从而有助于最大化光通量。描述和示出了其他实施例。
主权项	1) A light delivery apparatus for a photoplethysmographic device comprising: a. a series of two or more optical elements; b. the series of two or more optical elements arranged to conduct light from a laser; c. at least two consecutive elements of the series of two or more optical elements coupled together by a non-reflective coupling; whereby the non-reflective coupling minimizes back reflection and light loss as light propagates across the non-reflective coupling.
