I took a glass slab and gave the incident angle to be 45 degree. But as soon as I try to correct the lateral shift induced by decentering the image plane, my theoretical value do not match with what zemax is giving. Apparantly I realised that the value zemax is giving is similar to the value we get while we calculate for displacement due to secondary reflection and dividing it by half.&nbsp;&nbsp;&lt;\/p&gt;&lt;p&gt;Why does zemax considers value of displacement due to secondary reflection and not the lateral displacement?&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-422692","topic","type-topic","status-publish","hentry","topic-tag-displacementcondition-1","topic-tag-optics","topic-tag-opticstudio"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27816"],"_bbp_topic_id":["422692"],"_bbp_subscription":["519887","473055","284763"],"_bbp_author_ip":["2401:4900:1cb8:b9b7:f1d7:e721:e6a3:1e25"],"_bbp_last_reply_id":["424403"],"_bbp_last_active_id":["424403"],"_bbp_last_active_time":["2025-03-05 10:55:59"],"_bbp_reply_count":["5"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["3"],"_bbp_engagement":["519887","473055","284763"],"_btv_view_count":["201"],"_bbp_topic_status":["unanswered"],"_bbp_notification_enabled":["519887","473055"],"_edit_lock":["1740154203:473055"]},"test":"dr22phc1r46student-nitw-ac-in"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/422692","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/422692\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=422692"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
