DH-2000氘-钨卤组合式光源在一个光路中集成了氘灯光源和钨卤光源的连续输出光谱，产生215-2000nm的稳定的光谱输出。另外紫外增强型光源的输出光谱的范围为190-1700nm。
DH-2000氘-钨卤组合式光源有可由开关或 TTL信号驱动的集成快门。还可以选择在系统中添加一个可放置厚度高达4 mm、**为25mm的方形、**为20mm的圆形滤光片的滤光片支架。DH-2000的所有型号都有一个SMA 905接头，可通过光纤方便地与我们的光谱仪和附件相连，还有一个用于在没有连接光纤时阻挡光线通过的安全快门。
DH-2000所有型号的光源背后都有一个用来平衡氘灯光源和钨光源的光线强度的电位计，它允许用户在10-100%范围内调整氘-钨灯的功率。
对所有型号的DH-2000，我们推荐使用抗紫外光纤。
